Boiler (Steam and Hot Water) There are now two (2) ways of treating the water and boiler against scale and corrosion due to water quality. As specified and traditional, you can treat the water so that it has little influence on the metal components of the boiler. The successfulness of this traditional water treatment program approach is highly dependent on the attentiveness of the boiler operator. If you are treating the water to prevent it from scaling or corroding the metal component of the boiler, then per shift water testing is required to adjust the level of chemicals for: 1. oxygen scavengers to prevent metal oxygen pitting 2. scale prevention residual levels to prevent the accumulation of calcium and magnesium components of carbonates acting as an insulator costing the heat rejection surfaces 3. steam line corrosion in the form of carbonic acid. An Alternative Proven method is to treat the boiler components by filming the metal surfaces so that water has no influence on the metal surfaces. Such a chemical is Cetamine. Cetamine exhibits filming properties due to its hydrophobic tendencies (the desire to "leave or get out" of the water) so that water at any state or condition, cannot corrode the metal heat exchanger surfaces. This includes all corrosion mechanisms the most common being general surface corrosion, oxygen pitting and carbonic acid attack. Cetamine also imparts charges on the metal surfaces and extending into the water that will not allow deposits to form on the Metal Surfaces due to its hydrophilic tendencies (the desire to be in water). Simply stated, metal filmed with Cetamine cannot scale in that scaling components cannot precipitate on the metal due to the similar charges extending from surfaces of the metal into the water (like trying to put two similar ends of a magnet together, the similar charges will repel each other}. In reality, we have experienced Cetamine de-scale scale boiler systems, driving the efficiency to "like new" heat rejection capacity and efficiency. This product has been used in Europe for years, but has only been commonly available in the USA for less than two years. At this point, it has now been proven to be effective throughout the USA as it continues to be throughout the World. Pacific Water Technologies is realizing great success in boiler applications with Cetamine V217. At a Hanford fertilizer manufacturing facility, an new 600 HP incinerator boiler was installed and delivered with "tubes partially rusted" due to hydronic testing and not being properly dried prior to shipping of the boiler. After 8 months of operation, the tubes are deposit free with no evidence of any type of corrosion. In fact, all surfaces appear as though the tubes were polished and in better condition than originally delivered by the manufacturer. The boiler is delivering the steam volume as specified at the specified operating pressures and natural gas consumption. On another project, the boiler was scaled due to a failed water treatment program. With the change to Cetamine, the Boiler is experiencing de-scaling, the natural gas consumption has been reduced by 6% in the first 3 weeks of operation, and the Plant is reaching designed operating steam pressure 30 minutes sooner than before Cetamine. The cost of chemical treatment of this 300 HP fire tube boiler was reduced by 55%, from $12,000 per year to $7000 per year. If the County wishes to investigate the use of Cetamine for treatment of the Steam and Hot Water Boiler Systems, which the investigation is highly and strongly recommended, Pacific Water Technologies can develop a changeover cost. With regards to the steam boilers, the Cetamine simply replaces all of the current chemistries. This can be done over time by removing one traditional chemical at a time or replacing all of them at once. Pacific Water Technologies recommends a one-by-one replacement until the desired Cetamine residual is reached from this point forward only Cetamine would be required. In Hot Water Boiler Systems, it is best if the piping loops are cleaned, flushed and drained, it is also best if the System can be made-up with soft water (but with low hardness waters like in areas of Fresno, this may not be required) and Cetamine added to prevent scaling, corrosion, biological growth. The cost of Cetamine is $5.12 per pound including sales tax and freight. In the event you choose Cetamine the volume of chemical is greatly reduced to some 25% of what was originally estimated. NOTE: A similar approach (without the need for soft water) can be used for the Chilled Loops. Changing the formulas from the specified chemicals to Cetamine, the cost of Cetamine is $5.12 per pound plus tax and shipping cost. The cost of draining the closed loop systems needs to be determined and added to the overall cost. The benefits include a Chemical use reduction of up to 75% and improved program results with extended excursion (program upset) forgiveness. It is Pacific Water Technologies understanding that the chemistry currently applied throughout the various systems found in the Fresno County Facility Portfolio was designed to aid in on-line cleaning of existing deposits as well as to prevent the ongoing scaling and corrosion of the metal surface in the County's heat rejection equipment. The core program has been adjusted and modified over the years to the "real life" operations. Most importantly, due to Staffing issues, the chemistry was designed to be very tolerant and forgiving to program upsets to extend the response time for correcting program upsets and/or the in ability (due to limited staff and therefore time) of County Personnel to properly service the treatment programs. The existing Chemistries extend the time required to correct treatment issues prior to compromising the integrity of the system. Yes, even with the heavily concentrated, high quality, high performance components built into the treatment chemistries, some systems have still ailed in terms of integrity losses. Pacific Water Technologies agrees with Fresno County that the failures are not due to a lack of performance in the chemistry, but in the inability of your personnel (mostly due to the lack of labor due to a staffing shortage)to follow the required guide lines for a successful water treatment program. The fact is that it is not arguable that the original chemistry is very tolerant to allowing mistakes/upsets without immediately compromising the integrity of the treated system. Therefore, if formulation changes are made simply and solely in attempts to reduce the cost per pound of product, the "forgiveness factor" will, without any doubt, be compromised. Again, some systems have already suffered program failures and system integrity losses due to the lack of attention even with the Superior Raw Materials at elevated concentrations currently implemented. Fresno County will surely increase the exposure to system failures with lower cost chemical formulas. Therefore, there it is reasonable to believe Fresno County will experience more failed systems. For the reasons above that have been proven to exist, Pacific Water Technologies highly and strongly recommends the County of Fresno continues with the current chemistry until a time in the future where the County is fully staffed. It will also be important that Pacific Water Technologies has provided all training required such that all participating Staff Members are highly competent and proven reliable to allow for a lesser program "forgiveness" that will be afforded with any lower cost product. Pacific Water Technologies position is that if the staff remains as demonstrated over the past 5 years, the program with less expensive product and therefore, less tolerant upsets, will result in a dismal failure. Again, we recommend staying with the specified chemistry formulation at this time. Objective 1175 E.

The owner has been in the business for 42 years designing and installing the same type equipment for which the water treatment system will service. We are keenly aware understand how successful water treatment systems work and we also understand how the equipment is to operate for a successful water treatment program. Many times we have corrected failed treatment programs by correcting equipment operating conditions that caused the failure. In some instances, no matter what type or how much chemical would be used, the treatment program failed because the equipment was not being operated correctly. Our experience has allowed us to take over existing accounts with failed water treatment system. The heat rejection equipment is fouled with scale and biological growth. After the correction on the treatment system, the heat rejection surfaces were cleaned by use of our chemical formulas. An example would be the Federal Correction Facility in Mendota California. When we began work there taking over from a local water treatment firm, we found the three cooling tower and six boilers were scaled and fouled. We also found widespread corrosion in the cooling tower and iron components in the chiller's shell and tube condensers. After the change in treatment systems, the cooling towers no longer experience any corrosion (red rust) nor any wide spread fungus and mold. The chiller condensers remain scale free and no longer any corrosion. The boilers when we first arrived had widespread red rust throughout the boiler tubes. Since we took over, that issue has been resolved and no longer any corrosion or scaling of the tube surfaces. We have initiated start-ups of new mechanical systems from boiler boil out and passivation of the metal to cooing tower passivation and start-up procedures. Description of Similar Services: Ram co Services, Inc. currently maintains steam and hot water boilers. Some of the steam boilers are total steam utilization systems and some with 100% condensate return. We have converted boilers from soft water and filtered systems to reverse osmosis high purity water systems. Currently we are maintaining cooling towers on systems with 25,000 tons of refrigeration (TR) down to systems of 42 TR. Each of our accounts is design, specify, install, and service based on sound chemical engineering. Mr. Don Osborne will generally assist us in verifying our selection of a treatment system. At Sunview Cold Storage in McFarland, CA, our firm not only designed the entire 25,000 TR ammonia refrigeration system consisting of 26 evaporative condensers, we provide the water treatment system for all units. In the beginning more than 25 years ago, a large Fresno based water treatment company handled the account. The results of their care lead to nearly $1 million dollars in 2007-2010 in replacement ofthe equipment due to metal fatigue caused by corrosion. Since that point, we have taken over the account and all instances of corrosion and scaling have ceased. The personnel at the facility have been fully trained on their water treatment system and have since become self-sufficient in testing and adjusting their own equipment to maintain a successful water treatment program. Current Operations: Ramco Services is currently servicing firms that are willing to implement a water treatment program and not just provide chemical sales. Most of our clients are long term clients and typically began with the design and installation of their mechanical systems. Our goal is to do an exceptional job for a few selected clients ... We only take on new clients by referral knowing we can do the same exceptional job for them as we do for our current clients. We have our office in Clovis and as such, we would service the County's facilities twice per month as specified through this office Terminated Contracts: None Lawsuits: None County Payment Issues: None Scope of Work Discussion: For general discussion before presenting our scope of work discussion, we would like to offer some very relevant information about the County's project. Pacific Water Technologies was first awarded the 2014 contract for the County of Fresno HVAC water treatment program. Due to issues beyond our control, the project was rebid. In preparation, the company retooled our testing equipment to provide the most accurate testing and highest repeatability of those tests. The testing tools purchased were items such as Hach digital Colorimeters and digital pH/ TDS/ORP/Conductivity equipment. All of these portable devices provide the most accurate results in field test water san1ples. We use AquaPhoenix Scientific as out testing reagent supplier. As noted by the Association of Water Technologies, AquaPhoenix is the leader in the industry in providing high quality, greatest variety, and lab support. Since RAMCO SERVICES, INC. was to begin the water treatment system contract in January 2015, we had new field test reports printed specifically to meet the testing needs and reporting by the County. We have attached a copy of the "Cooling Tower" report form and the "Boiler" report form for your review. The water test results will be recorded in a Cloud Based data center. The software is produced by H2Tronics in Dallas, Texas. We will record our findings after each test period. The software records the data and analyses it for acceptable ranges, deviations by percentage from normal, and those results out of bounds. The software by color change technology, lets the operator know if the results are normal (green color fill) or slightly out of range (yellow for caution for further examination) and red color fill if the results are way out range and needs immediate attention. The program can email or text messages to you for alarms as well. The software is secure by passwords, and allows the operator to review data, see max/min/averages of the test results, inventory of chemicals and supplies, alarm and exception reports, and includes a maintenance log. All of the data is available to County personnel permitted to gain access to review the data via the internet. The County will have its own passwords, and each building is listed, and the data fields in the reports required for reporting is provided. All training is included to those employees that will be using the software. This service is included at no-charge to the County. Pacific Water Technologies has taken very serious the water treatment program. As explained above, we took extraordinary measures to ensure the County that we would provide the most accurate, the highest quality products, the absolute best water treatment program. None of the above was a contract requirement, but we took these measures to do the very best that a company could do to ensure the quality required for a successful water treatment progran1. Pacific Water Technologies uses as its reference the documentation ofthe Association ofWater Technologies, ASHRAE, EPA, WHO, and writings provided by university studies in unique studies, for our base reference in procedure and expected results. We DO NOT allow "mle of thumb" procedures into our business! Explanation Bv Section the Scope of Work The sections below are from the bidding documents.

We typically recalibrate on a monthly basis or as recommended by the manufacturer of the device. 8.7. RAMCO SERVICES, INC. will note any failures in the water treatment equipment at the time of testing. We will make recommendations to a remedy at that time to the County staff onsite and to the management authorities. 8.8 RAMCO SERVICES, INC. will at the specified interval of90 days, remove and replace the metal coupons in the racks. The existing coupons will be immediately sent to the lab for results. Each coupon has a unique serial nwnber and at the time of replacement, the new serial number will be recorded in the field test report. 8.9. RAMCO SERVICES, INC. will inspect each site for defects. We will look for piping and tubing leaks, equipment failure or maintenance issues, storage of the chemicals to meet safety requirements, calibrate all existing device such as conductivity sensors, confirm the MSDS (SDS) and equipment IOM manuals are onsite and near the chemical treatment system and each chemical is properly labeled from the manufacturer. All of the inspection information will be logged into the field test repmi. Section 9.1 through Section 9.3 This section defines the residual levels of chemical to be maintained in the equipment. We are fully aware of those levels and will maintain those levels as defined. The County staffwill also be trained to adjust equipment to maintain these levels, and most impmiantly is why they need to do so. We will teach the staff the importance of maintaining a particular specified residual level and what it means to do so and the expected outcome. We will explain why NOT do so will lead to unintended consequences. Section 10 Equipment 10.1 Cooling Towers RAMCO SERVICES, INC. will provide the bleed and feed control concept of chemical control, dispensed automatically through an approved metering pump. The chemicals will be stored in an approved double wall tank provided by the County through this project or through any other means. The water bleed is controlled through an electric solenoid valve and interlocked to the controller with conductivity sensor. IfRAMCO SERVICES, INC. is asked to provide any new piping, we will uses as specified either copper tube or schedule 80 PVC pipe and fittings. There are several methods of chemical feed. If the type of feed needs to change by regulation, we will assist the County in making those changes. In any chemical treatment system, the controller, conductivity sensors, safety flow sensor, metering pump, and bleed valves should be interlocked electrically and sometime mechanically. 1 0.2. Closed Loop Systems RAMCO SERVICES, INC. will be using the existing chemical pot feeders previously installed and exist. We will introduce the chemicals through the feeder and will make adjustments to the hand valves and bypass valve (all existing) to properly add the chemical to the water systems at the proper level. Using the pot feeders and introducing the chemicals will be done so using acceptable industry methods and the recommendations ofthe manufacturer. 10.3. Steam Boilers RAMCO SERVICES, INC. will use the existing metering pump and controls to introduce the chemicals into the boiler, i.e. directly into the boiler or into the feed water tank determined by the existing method of piping currently installed. The goal of any successful water treatment program is to prevent scale and corrosion. We know to be true that the only acceptable answer to the questions of"does your boiler have any scale or corrosion" is NO! A "little bit" or "some" is never acceptable and will make great strides to ensure the County that the boiler is scale and corrosion free. At times of"wet lay-up" of an inactive boiler, we will or help your stafflay it up by documented and precise procedures step by step to do so. The County staff and administration will be given a written procedure of how we will lay up the boilers knowing it was done exactly, correct, and no short cuts taken. All assurances and methods will be taken to prevent chemicals that are not suitable for food contact, to be kept separate and allow for no cross contamination. Most of the chemicals specified are FDA and/or USDS approved. Section 11 Water Treatment Equipment New/Repairs/Replacement RAMCO SERVICES, INC. is familiar with your operating schedule and will cooperate to any seasonal change to the operation as determined by the County. We will never dictate when you shall operate, but rather will work diligently to do the work as you determine the operating season of your equipment. RAM CO SERVICES, INC. will, at its expense and permission from the County, repair or replace any deficient tubing that may cause immediate or imminent harm to us or the County's employees. At the end of the season, RAMCO SERVICES, INC. will assist your staffing determining the best way to "winterize" your system. We will provide a report noting any repair necessary for "winterizing" or required for the next year start-up. We will secure the chemicals for storage to prevent degrading or oxidation of the product. Section 12 Definition of Operating Season 12. Cooling Towers RAM CO SERVICES, INC. understands the serviced and taken offline by the County schedule and will accommodate this per specification. We will cooperate if any operation or change in use dictated by the Cotmty has to occur. 12.2 Closed Loop RAMCO SERVICES, INC. understands the closed loops are serviced year round and will do so per specification. We will cooperate if any operation or change in use dictated by the County has to occur. Section 12.3. Steam Boiler Program RAMCO SERVICES, INC. will follow a define start up procedure provided by us or a method that the County has determined best for their equipment. This would include the draining, refilling, and chemical re-dosing. RAMCO SERVICES, INC. has a specific "lay-up" procedure to offer the County. We will use this method unless the County has a procedure they would like to use. In either case, the lay-up will be successfully completed. All steam and hot water closed loop systems are to be maintained and treated year round unless placed into storage by the County. Section 13. Safety Data Sheets RAMCO SERVICES, INC. will submit MSDS (SDS) sheets in a 3-ring binder for each site and placed in the area of the water treatment system. The binder will be organized by boiler, towers, and closed loop systems for easy access to the information. Please see attached MSDS (SDS) in this bid package as well. Each chemical drum or storage double all tanks will be properly labeled as well from the manufacturer or by RAMCO SERVICES, INC .. Section 14. Reports RAMCO SERVICES, INC. has printed a special field test report for Fresno County work. See attached sample in the bid package. The report will be reviewed with the staff at the time of testing and a copy left in a field test report binder. A copy will be emailed with 10 days of the testing to the County officials. Also, a Cloud based data system by H2Tronics will be used for continued reporting and analysis. The County at any time can access the reports and see the analysis by logging onto the our site, logging into the County facility site, and viewing the reports and reviewing the analysis, Section 15. Legionella RAMCO SERVICES, INC. will test ofLegionella as well as fungus and molds at the time of testing. A special container will be provided for the sample and shipped in a chilled container for local testing with the noted water temperature at the time the sample was taken. If the report detects unsafe levels of Legionella, then the written procedure for decontamination will be provided. The written procedure will be provided to the County before the work begins. All care will be taken for safety, contamination, and infection. All tests will be provided in a written report from the testing laboratory. Section 16. Off-Line Cleaning Procedures for Cooling Towers All towers will be cleaned as prescribed by the County. All chemicals used will be provided with MSDS (SDS) sheets before beginning as scheduled by the County. The types of chemicals, dosages, and techniques will be followed as prescribed by the County or by RAMCO SERVICES, INC.'s written procedure as the County prefers.

Water Product Information :· www. wateradditives.com BromiCide®-The Number One Oxidizing Biocide for Industrial Water System Description and Use BromiCide oxidizing biocide is a safer, more effective alternative to chlorine based oxidizing biocides and non- oxidizing biocides for microbiological control in industrial cooling waters. In water, BromiCide granules generate hypobromous acid, a highly effective oxidizing biocide, especially at high pH. BromiCide is registered with the United States Environmental Protection Agency for use in once-through and recirculating cooling waters, heat exchange water systems, air washers equipped with mist eliminators, industrial water scrubbers, influent water systems, brewery pasteurizers, cooling ponds, wastewater treatment systems and pulp and paper mills. Benefits • Broad spectrum effectiveness. BromiCide kills a broad variety of bacteria, algae and fungi and because it is an oxidizing biocide, microorganisms cannot develop resistance. • Effective in a wide range of water conditions. BromiCide provides excellent performance in alkaline water situations as well as in waters containing nitrogen and organic materials. • Low dose performance and safer handling. Since BromiCide is effective at low doses, maintaining high halogen levels is unnecessary. This means less product is needed, at less expense. Its solid form also makes BromiCide is easier to handle than gas and liquid oxidizing biocides, reducing the risk chemical accidents and impact of environmental exposure. • Controlled dissolution. BromiCide can be applied in easily controlled do.ses because of its unique solubility characteristics. Users have the freedom to decide the required dissolution rate and then select the BromiCide product to fit their needs. BromiCide granules are the product of choice where rapid attainment of a halogen residual is required. BromiCide tablets dissolve more slowly that granules and are the product of choice where a high degree of feed control is needed. Treatment and Dosing Requirements BromiCide effectively controls bacterial, algal, and fungal slimes that can cause costly reductions in heat transfer efficiency. BromiCide can either be dosed on a continuous or intermittent shock basis using erosion feeder dosing systems (brominators). For noticeable fouling, add 0.2 -0.5 ppm as Cl2 for continuous dosing, or 1 -2 ppm as Ch for intermittent shock dosing. Typically, in well managed systems, successful control has been demonstrated with dosages in the range of 0.1 -0.3 ppm total halogen as Ch. Typical Properties of BromiCide Products Active Ingredient 1-bromo-3-chloro-5, 5-dimethylhydantoin (BCDMH). Solubility@ 25° C: 0.2 % as BCDMH Active Ingredient: 96% Melting Point: 145 -150°C (decomposes) BromiCide granules are white to off-white in color and have a faint halogen odor. Bulk Density: 57 lb/ft3 (915 g/1) BromiCide tablets are white to off-white in color and have a faint halogen odor. Tablet Dimensions: Tablet Weight: 1 3/16" X 3/4" (30 x 19 mm) 20grams Storage and Handling Precautions BromiCide products should be kept dry in a tightly closed container. Avoid contamination with moisture, chemicals or any other foreign materials due to risk of explosion, fire and release of hazardous gases. Store in a cool, dry, well-ventilated area away from heat, sunlight, open flames and organic materials such as greases, oils and solvents. BromiCide is corrosive in solution, and may be fatal if swallowed. Inhalation of dust may cause irritation of the nose and throat, and irritation to skin. Always wear a dust mask approved by the appropriate national authority, impact- resistant safety goggles or safety glasses, and a full-face plastic shield with forehead protection. To avoid contact with skin, wear rubber or plastic gloves, long pants, and long shirt sleeves. Always tuck gloves under shirt sleeves and leave pant legs outside of boots. Wash contaminated clothing and equipment before reuse. Safety Precautions Do not leave wet BromiCide exposed to air inside a brominator feed system. After adding BromiCide but before replacing the top closure, refill the tank with water. Failure to do so may allow for product decomposition leading to pressure build-up in the feeder. High pressures may lead to rupture of the feeder causing serious bodily injury or property damage by explosion, fire or release of hazardous gases. Patents Contact of BromiCide with organic materials such as alcohols, aldehydes, and ketones or strong reducing agents may cause a chemical reaction leading to a pressure build- up in the feeder. High pressure may lead to rupture of the feeder causing serious bodily injury or property damage. Before handling BromiCide products, all persons must be thoroughly aware of the hazardous properties and have reviewed the Material Safety Data Sheet (MSDS). A MSDS may be obtained from BWA Water Additives. Always use biocides safely. Packaging Information BromiCide granules and tablets are available in 25 lb (11.4 kg) pails; 50 lb (23 kg) pails or 500 lb (225 kg) bulk bags.

BW A Water Additives UK Limited is a private limited company registered in England and Wales at 2 Brightgate Way, Manchester M32 OTB, Registered No. 5657343 WaterfrontTM Product Information :· www.wateradditives.com Bellacide® 355-Next Level Synergistic Biocide for Industrial Water Systems Bellacide 355 provides enhanced performance as a fast acting, broad spectrum biocide with superior activity compared to other non-oxidizing biocides. In particular, its unique properties set it aside from simple cationic ammonium and phosphonium biocides. Bellacide 355 is designed for the control of microbiological fouling in cooling water, industrial and institutional cleaning, oil field waters, papermaking and other industrial water applications. Heavily fouled systems can be cleaned using Bellacide 355 since it is highly effective in preventing the build-up of microbiological slimes. Previous work has shown that Belladde 355 works synergistically with oxidizing biocides such as BCDMH and chlorine. (hypobromous and hypochlorous acids) however, new data confirms that it is also synergistic with chlorine dioxide and peracetic acid. Other industrial biocides do not show synergy with this range of oxidizing biocides whereas Bellacide 355 is proven to enhance their performance significantly. Advantages of Bellacide 355 • Cost effective, broad spectrum of activity Bellacide 355 has a high activity at low dose levels against aerobic bacteria (including Legionella pneumophila), anaerobic bacteria, algae and fungi with typical MIC values of 20 and 100 ppm for algae and fungi respectively. Compared to other non-oxidizing biocides it is quite fast acting. • Minimize biocide usage by synergistic effects Bellacide 355 offers a unique synergistic interaction with oxidizing biocides allowing a significant decrease in usage of oxidizing biocides in industrial water systems. This effect is achieved at dosage levels of Bellacide 355 that are very economical. " Reduction in environmental impact and biocide cost The excellent synergistic biocidal effects, high surface activity and low foaming properties make Bellacide 355 a great pairing with oxidizing biocides to minimize biocide usage volumes thus reducing the environmental effects and cost of the biocide program. • Compatible and easy to use across broad pH range Bellacide 355 mixes uniformly in water and is not affected by the pH of the system water, being applicaple from pH 5 to 12. At normal use levels it is compatible with other water treatment additives commonly found in open recirculating cooling water systems and can be used with oxidizing agents. Bellacide 355 is not susceptible to degradation by ultraviolet light. Synergistic Activity of Belladde 355 ... . .. with chlorine dioxide (CI0 2): On its own chlorine dioxide showed minimal activity at 0.1 ppm active against a common type of cooling water organism. Bellacide 355 also showed a limited reduction at 5 ppm active after 10 minutes but gave a complete kill after 30 minutes. The combination of Bellacide 355 and chlorine dioxide showed better activity than the individual products with close to a 5 log 10 reduction after only 10 minutes. Control CI02 Bellaeide 355 Bellacide 355 + CI02 •.. with peracetic acid Using the same test protocol, peracetic acid, a mixture of peracetic acid and hydrogen peroxide, showed limited biocidal activity at 1 ppm (as peracetic acid) at 10 minutes but gave essentially a complete kill after 30 minutes. As noted previously, Bellacide 355 showed limited activity at 5 ppm active at 10 minutes. However, the combination of Beltacide 355 and peracetic acid showed excellent synergy and provided greater than a 6 log 10 reduction (complete kill) after only 10 minutes. Perncotie Acid Bellaeide 355 Bellaelde 355 + Peracetic Acid .•• with bromine sources such as BromiCide and sodium bromide In this series of tests, BromiCide (BCDMH) yielded a 4 log 10 reduction in bacterial counts at 0.2 ppm residual (as Cl2) after 10 minutes and Bellacide 355 showed a half log 10 reduction at 5 ppm active at 10 minutes. The combination of Bellacide 355 and BromiCide showed significantly better activity than the individual products giving a greater than 7log10 reduction (complete kill) after 10 minutes. BrorriOde BeUaclde 355 Beftacide 355 + Brorriade ... with chlorine Likewise, chlorine showed a 4 log 10 reduction in bacterial counts at 0.2 ppm residual active after 10 minutes. The combination of Bellacide 355 and chlorine displayed significantly better activity than the individual products providing greater than 6log10 reduction after 10 minutes. Summary This extensive series of testing has confirmed that the synergy effect of Betlacide 355 is not limited to only one type of oxidizing biocide but rather extends across a range of oxidizing agents. This is consistent with the chemistry of TTPC (Bellacide 355) and also explains why it is very effective at removing biofilm. When combined with oxidizing biocides, Bellacide 355 offers unprecedented opportunities to optimize biocide programs both in terms of biocidal performance as well as minimizing their environmental footprint. Typical properties Bellacide 355 is a 50% aqueous solution of tributyl tetradecyl phosphonium chloride (TTPC). Appearance Specific gravity at 20°C pH Odor Solubility: Water Methanol Isopropanol Ethylene glycol Determination of Bellacide 355 Clear, colorless liquid 0.98 g/ml 7.0-9.0 Slight Completely miscible >50% >50% >50% A simple colorimetric method is available for the determination of Bellacide 355 in industrial cooling waters.

CONFIDENTIAL BWT-1 PRODUCT DESCRIPTION: Fresno Connty had BWT-112 developed specifically for the removal of Oxygen in the Feedwater Storage Vessel associated with Steam Boiler systems. The product is liquid and easily applied to the storage section of any Feedwater Tank/Deaerator. BWT-112 is a catalyzed, highly concentrated Sulfite blend. As a catalyzed sulfite, BWT-112 will most rapidly react with Dissolved Oxygen. The Sulfite bonds with the Oxygen forming Sulfate. This reaction renders the Oxygen unavailable to react at the metal surface. This reaction takes time and higher concentrations of Scavenger in ratio to existing Oxygen to complete. To avoid oxygen pitting, 100% of all available Oxygen must be removed. Therefore, it is necessary to drive off as much of the Oxygen as possible through raising temperature and pressure prior to injecting any Oxygen Scavenger. It is also important to assure that the Feedwater storage volume is adequate in providing the required contact time for complete reaction. BWT-112 should always be fed alone and introduced to the system using a flow switch to activate the Chemical Feed Pump with any System Make-up flow. It may also be injected slowly on a continuous basis. BWT-112 is effective in protecting the Boiler and Condensate Systems waterside surfaces against Oxygen Pitting corrosion in these otherwise highly corrosive environments. BWT-112 is a proprietary blend of high performance raw materials designed to control corrosion within Industry Standards. BWT-112 has been blended with a unique ratio of raw materials. The specific ratio allows for a single Sulfite test to be used to control the product feed rate. PRODUCT SPECIFICS: Priority Water Quality Limits: Always try to maintain Feedwater Temperatures and Pressures as high as possible without creating pumping issues. Requires 50 ppm BWT-112 per 1 ppm 0 2 • Feed to Feedwater Storage Vessel.

CONFIDENTIAL Product Ca:rd BWT-178 PRODUCT DESCRIPTION: Fresno County had BWT-178 developed specifically for inhibiting waterside deposition in Steam Boiler systems. The product is liquid and easily injected into the Feedwater line after the Feedwater pump and prior to the Boiler (if possible, within 12 Feedwater Pipe Diameters of entering the Boiler). BWT-178 contains a highly stable Phosphate, and a highly concentrated blend of Polymers. The Phosphate in BWT-178 provides the best stability available under the high temperature conditions found in High Pressure Boilers. The concentrated, proprietary blend of multi-function, high performance Polymers with the Phosphate provides Phosphate stability, Iron transportation and Hardness deposit inhibition. This combination of active functions, makes BWT -178 perfect for today's Steam Boiler applications. BWT -178 should be introduced to the system whenever Feedwater is flowing to the Boiler. The power to the BWT-178 feed pump should be tied to the power of the Feedwater pump(s) to activate the Chemical Feed Pump with activation of the Feedwater pump(s). BWT- 178 may be fed alone or mixed with Amines and/or Alkalinity Builders. BWT-178 is rated as Non-Hazardous. BWT-178 has been blended with a unique ratio of raw materials.

This document has been produced by the Technical Committee of AWT and authored by William E. Pearson II, CWT. Special thanks is given to the Cooling Water Subcommittee project and review team including J. Patrick Sisk, Kenneth R. Davenport, Richard W. Gilpin, Ph.D., Robert D. Lee, CWT, Gary M. Reggiani, Charles T. Smith, CWT and Chris L. Wtatr, Ph.D. in addition to document reviews by Matthew R. Freije and Janet E. Stout, Ph.D. for their (continued) gracious contributions of time, expertise and knowledge toward the production and technical review of this document. Warning and Disclaimer This document is designed to provide information on the subject matter. It Is produced with the understanding that neither AWT nor the author (or other contributors) is rendering legal, medical, engineering, or other professional services. Neither A WT nor the author (or other contributors) shall be liable for damages, in any event, for incidental or consequential damages caused, or alleged to be caused, directly or indirectly, by the use of any information disclosed in this document, including the use of any recommendations, methods, products, services, instructions, or ideas. Forward The Association of Water Technologies (AWT) is a not-for-profit, international trade association founded to serve the interests of regional water treatment companies and to advance the technologies of safe, sound and responsible water treatment practice. AWT provides education and training, public awareness, networking, research, industry standards and resource support. Association activities are directed towards promoting the growth and development of member firms and advancing the arts and sciences of the water treatment industry. Since the initial outbreak in 1976 that led to the discovery and identification of Legionnaires' disease, much has been discovered about the bacteria (Legionella) that causes the disease and the disease itself. This includes how Legionnaires' disease is contracted and how to minimize risk of disease contraction, as well as effective medical treatments for Legionnaires' disease. However, guidelines for "1 00%" disease prevention and control remain at large, as well as any uniform consensus on the routine testing (monitoring) for Legionella in the water systems that may harbor the bacteria. Existing guidelines and statements, however, do provide substantial direction and information that can be adopted to effectively control and minimize legionellosis. This document is a comprehensive update of collective information and data available from numerous research, investigative, and authoritative sources on Legionella and legionellosis. These include the CDC (Centers for Disease Control and Prevention), OSHA (Occupational Safety and Health Administration), WHO (World Health Organization), EPA (Environmental Protection Agency), various state public health agencies, as well as associated technical trade organizations and recognized Legionella experts and commercial entities. Due to the multi-disciplined, technical and medical nature of the subject, this document is directed at summarizing and presenting Legionella in an up-to-date, informative, and useful format to the water treatment professional and end-user, as well as for the general public. Extensive references are cited that may provide more detailed and in-depth information on legionellosis and related topics to benefit those with more specific interest and application or decision making needs. 2 Legionella 2003 -Update and A WT Statement LEGIONELLA 2003: An Update and Statement by the Association of Water Technologies -©2003, Association of Water Technologies, Inc., All rights reserved. www.awt.org Page I.

I. Background: Discovery of legionnaires' Disease & Legionella Legionnaires' disease (LD) acquired its name from the media reference given to a mysterious pneumonia-like illness that afflicted numerous attendees of an American Legion convention in Philadelphia at the Bellevue-Stratford Hotel during July of 1976. An outbreak of illnesses occurred presenting Pennsylvania Department of Public Health officials with a recorded 221 cases of a strange respiratory illness contracted by convention (hotel} attendees and by some hotel pedestrians. Symptoms included high fever, chills, muscle pain, headache and eventual development of a dry cough with difficulty in breathing. Some patients developed patchy lesions in their lungs representative of severe pneumonia. More than two-thirds of the patients required hospitalization and 34 eventually died. Investigation of the outbreak by the Centers for Disease Control and Prevention (Atlanta, GA) led to the eventual discovery of the causative agent, a bacterium, in January of 1977. The bacterium was subsequently named Legionella pneumophila (pneumophila is Greek for lung-loving). It was determined that neither the bacterium nor the disease was new and that Legionella bacteria have been around and causing disease for many years. When reexamined, the CDC found Legionella bacteria in fifty-year old (archived) tissue samples of unsolved and similar-illness cases. So, Legionnaires' disease was not a new disease discovered in 1976-just an old one that was finally recognized and named. 4 Legionella 2003 -Update and A WT Statement II. Background: Terms, Definitions, & General Facts Legionella is the name for the genus of bacteria. Legionellae (the plural, referring to more than one Legionella bacterium) are aerobic, non-spore forming, rod-shaped, typically flagellated, gram-negative bacteria. They are common to aquatic, especially warm water, environments and some soils. There are 43 or more identified species of Legionella, with more than half being linked to human disease. Some Legionella species are made up of multiple serogroups, with over 60 serogroups presently identified for the genus. Many of the species serogroups are further differentiated into numbers of subtypes. legionellosis is the collective term describing any illness caused by exposure to the bacterial pathogen Legionella. Legionnaires' disease and Pontiac fever are the two most common types of legionellosis, with Legionnaires' disease being the more serious and primary one of focus. It is an environmental disease-with the causative agent (Legion ella) transmitted from an environmental source (water or soil) to a host. It is not transmitted from person to person -thus, it is not a communicable disease. Legionella pneumophila (Lp) is one species of Legionella-and is the causative species to more than 90% of legionellosis cases. More than 70% of these cases are attributed to one serogroup of the more than 15 Lp serogroups -Legion ella pneumophila serogroup 1 (Lp-1 ). As it turns out, Lp-1 is the most common isolate recovered from environmental samples. Within Lp-1 are more than 50 subtypes that can be identified by phenotypic or molecular typing methods. Serogroups and subtypes appear to differ as to their particular degree of virulence. legionnaires' disease (lD) is an acute bacterial infection of the lower respiratory tract, i.e., a bacterial pneumonia. The disease is a potentially fatal, multi-system respiratory illness with an average mortality rate of 15-20%. Fortunately, it is selective in attack and infects only 2-5% of those appropriately exposed to the bacteria. • LD is a serious illness and not rare. Legionella bacteria are among the top three causes of sporadic, community-acquired pneumonias. American Society for Microbiology News (61 :621) ( 1995) reported that 15-30% of patients admitted to intensive care units with pneumonia had legionellosis. It is also the cause of many hospital-acquired (nosocomial) cases of pneumonia. Many LD cases go undiagnosed because the disease is difficult to distinguish from other forms of pneumonia -unless specifically targeted. Even when detected, it often goes unreported to the public health authority, especially if cases are sporadic (one or two-case incidents) and not associated with an outbreak investigation. The under-detecting and under-reporting of LD makes its incidence difficult to estimate and why such figures vary widely. The CDC has estimated that the disease infects 10,000-15,000 persons annually in the US. OSHA estimates that over 25,000 cases of the illness occur each year, causing more than 4,000 deaths. Still, others estimate as many as 100,000 annual cases. 5 Legionella 2003 -Update and A WT Statement .. lD Exposure is most likely to occur via: 1. Inhalation: of aerosols, fine sprays, mists or other microscopic droplets of water (or soil) contaminated with Legionella -providing direct access into the lungs; and/or 2. Aspiration: such as may occur when choking or spontaneously during the drinking, ingesting, swallowing process-allows oral fluids and/or particles to by-pass natural gag reflexes and enter into the respiratory tract and lungs instead of the esophagus and stomach. • lD Sources may include almost any warm water system or device (man-made or natural) that disseminates water, particularly as aerosols, sprays or mists and provides favorable conditions for Legionella growth and amplification. A notable source of Legionella today, contrary to the long association and thinking that cooling towers are the only significant source for LD, is the domestic (potable water) plumbing system. These systems in large buildings and/or complexes including, but not limited to, hotels, institutions and health care facilities have been commonly linked to occurrences and transmission of LD. Current data suggest that cooling towers and evaporative condensers, while still potential LD sources, may be an overemphasized modal of disease transmission. Other LD sources include: various heat-rejection devices, humidifiers, showerheads, faucets, whirlpool baths and spas, hot springs, respiratory therapy equipment, and even misting machines found in grocery store produce sections. .. LD Susceptibility is an important factor in disease contraction. The greatest host susceptibility to Legionella is found in the elderly and those with suppressed or compromised immune or respiratory systems. This includes: heavy smokers, alcoholics, HIV patients, cancer, bone marrow or organ-transplant patients, and others with lung or respiratory diseases. Underlying disease and advanced age also contribute to a significantly higher risk of mortality with LD. The most common risk factor found in LD patients is heavy cigarette smoking, along with chronic lung disease. Bone marrow and organ transplants represent the most intense risk factor, since the medicines used to protect new organ transplants also compromise the body's immune defenses against infection. Patients taking corticosteroid medicines are also at risk. • LD Symptoms may include: ..._ High Fever, Chills, Headache, Muscle Pain (Flu-like symptoms), 11!1> Dry Cough and Difficulty in Breathing, ..._ Diarrhea and/or Vomiting, and 11!1> Confusion and Delirium • lD Incubation period is 2-1 0 days. This is the time it takes, after exposure, before symptoms of the illness appear. For several days, the patient may have flu-like symptoms and feel tired and weak. Most patients who are admitted to a hospital develop high fever, often greater than 39.5°C (103°F). A cough can be the first sign of a lung infection and may be sufficiently severe to cause sputum production (mucous with saliva). Gastrointestinal symptoms are seen in approximately 40% of patients, with diarrhea the leading symptom. Many patients have nausea, vomiting, and stomach discomfort. Other common symptoms include headaches, muscle aches, chest pain, and shortness of breath. • lD Treatment requires the use of antibiotics. However, many antibiotics effective 6 Legionella 2003 -Update and A WT Statement against other bacterial pneumonias are ineffective against Legionel/a as they do not act to penetrate the pulmonary cells (alveolar macrophages) where infectious Legionella thrive. Fortunately, there are several newer antibiotics that are effective on Legionella. The two most potent classes of these antibiotics are the macrolides, such as azithromycin, and the quinolones, including ciprofloxacin, levofloxacin, moxifloxacin, gemifloxacin and trovofloxacin. Other agents that have proven effective against LD include tetracycline, doxycycline, minocycline and trimethoprim-sulfamethoxazole. Erythromycin, the former antibiotic of choice, has been replaced by these more effective and less toxic antibiotics. When LD patients are treated with appropriate antibiotics near the onset of disease, the outcome is usually excellent, especially if there is no underlying illness compromising the immune system. For patients with compromised immune systems, including transplant recipients, any delay of appropriate treatment can result in complications, prolonged hospitalization, and death. After successful treatment and hospital discharge, many patients will still experience fatigue, loss of energy, and difficulty concentrating. These symptoms may last for several months. Complete recovery within one year is usually the rule. Patients who were cigarette smokers should consider discontinuing smoking. Pontiac fever is a much milder, non-pneumonic, flu-like illness caused by Legionelfa species. Cases of Pontiac fever have been linked to L. pneumophila, L. feelie and L. anisa. It attacks indiscriminately; uniformly infecting 90% to 95% of those exposed and has a shorter incubation period (than LD) of 1 to 3 days. Complete recovery usually occurs in 2 to 5 days without medical attention. Because the contraction of Legionnaires' disease (LD) represents a much more serious condition than Pontiac fever, this paper's information focus will be on LD and Legionella pneumophila (as well as other species of Legionella) that cause it. 7 Legionella 2003 -Update and A WT Statement Ill. Legionella: Infectious Growth, Transmission & Host Susceptibility Legionella are common warm water microorganisms. They are primarily found in surface waters (lakes, ponds, rivers and streams) but can also be found in ground water sources, including some soils (Legionella long-beachae). Legionella tend to grow in biofilm or slime on the surfaces of lakes, rivers and streams -and can easily adapt to conditions within water distribution systems. The ecology of Legionella is particularly interesting and is important to its ability to persist in the environment, as well as infect man. Legionella are protozoonotic-in that they live, reproduce and survive within certain free-living amoebae and ciliated protozoa as facultative intracellular parasites. In this relationship, the protozoa are obligate cellular hosts in which Legionella replicate and thrive, as well as gain protection from harsh, natural or man-made, environmental conditions. Chlorination, UV irradiation and chemical biocides all offer temporary means by which laboratory and planktonic Legionel/a can be eradicated from a water source. However, the majority of Legionella do not exist as free-swimming (planktonic) bacteria. Instead they reside, well-protected, inside protozoan hosts and in the matrix of biofilm. Eventually, they are released from their hosts in the form of small vesicles that may contain hundreds or a thousand or more legionellae per vesicle. In terms of survival, the amoeba-grown bacteria are better able to withstand their aquatic environment and may be more virulent. This adaptation and endosymbiotic relationship with amoebae and other protozoa allows Legionella, among other things, to survive typical potable water chlorination (disinfection) and appear in many finished water supplies to homes, buildings and industry. Thus, the mere presence of Legionella does not, in and of itself, result in disease. It is only when Legionella are able to 1) amplify (increase in population density), 2) present certain virulent factors and 3) gain transmission into the lungs of susceptible human hosts that they can cause LD infections. • Legionella must have certain strain-specific virulence factors to cause disease. They must also be present in sufficient quantity to cause infection. One gene (rtxA) is involved in the ability of Legionella to enter and cause toxic effects within host cells (Cirillo, S.L., et al., 2001 ). • A susceptible host must inhale or otherwise aspirate (choke into their lungs) water or particulates colonized with a sufficient quantity of virulent Legionella. If these Legionella-contaminated droplets are of respirable size (<5.0 micron), the Legionella can reach the deepest (alveolar) parts of the lung. There they are engulfed by pulmonary macrophages intending to defend the body against invading bacteria. However, instead of being destroyed (digested) by phagocytosis, the Legionella survive and actually grow (amplify) within the macrophages-as they do environmentally within amoebae and other protozoa. At their optimum (human body) temperature for growth, the Legionella amplify to eventually cause cellular lysis (rupture) of the macrophage cells. This soon overwhelms the host's immune system and promulgates the disease. 8 Legionella 2003 -Update and A WT Statement • The dose of Legionella pneumophila (or other species of Legionella) required to infect humans is not known. It is most probably influenced by host susceptibility. Growth & Amplification of Legionella: In order to better understand Legionella, its potential to cause disease and how to better control Legionella in water systems, we must understand the conditions that promote Legione/Ja growth and amplification. Major factors include: 1. Stagnant water conditions and/or system design configurations that produce stagnation, such as side-arm and dead-leg piping; 2. Warm water temperatures between 20 and 50°C (68 to 122°F); 3. Optimal growth is at temperatures between 35 and 45°C (95 to 113°F); 4. Bulk water pH in the range of 5.0 to 8.5; 5. Sediment, scale, deposits, biofilm-support not only Legionella growth, but also that of the very important supporting microbiota for Legione/la; 6. Microbiota, including algae and many bacteria that supply essential nutrients for growth of Legionella; 7. Certain amoebae and other protozoa that harbor Legionella as endosymbionts - allowing them to thrive, resist harsh environmental conditions (including biocides) and to significantly amplify. Many different types of water systems can serve as Legionella amplifiers and (aerosol) disseminators, and have been associated with LD. They include:. • Domestic Hot Water Systems (tap faucets, showerheads, sprayers), " Cooling Towers and Evaporative Condensers, • Spas and Whirlpools (on display or otherwise in use), • Humidifiers, • Decorative Fountains, • Supermarket Reservoir Misters, • Respiratory Therapy Equipment, • Water fountains, • Hot Springs (Waterfalls), and • Dental Hygiene Equipment.* * Note: as a potable water disseminator, should be considered a potential source of LD, however, it is not known to have been linked by direct subtyping to a known case of LD- although a great deal of media attention was given to a California dentist who died of LD a few years ago. Accordingly, due care and concern should be exercised in the operation and maintenance of these and other type water disseminating devices or systems as to their potential to harbor, amplify and transmit Legionella and to the potential health risk they pose to at-risk individuals. Transmission of Legionella: After growth and amplification of Legionella to potentially 9 Legionella 2003 -Update and A WT Statement infectious levels, the next requirement in the chain of disease causation is to achieve transmission of the bacteria (in) to a susceptible host. A widely accepted theory for the disease transmission of Legionel/a is that the organism is aerosolized (in water) from a water-disseminating system or device and is inhaled as tiny (micro) water-droplets, containing the bacterium, and gain entry into the lungs. However, another well documented mode of transmission that effectively gets bacteria into the lungs is "aspiration" -and evidence suggests that it may be the more common mode for Legionella transmission than previously considered. Aspiration is a "choking process" that can occur during drinking, swallowing or clearing-the- throat and during respiratory therapy. Aspiration is a common way that bacteria enter lungs and cause pneumonia. As it occurs, secretions or fluids in the mouth can get past the choking (gag) reflex and instead of going into the esophagus and stomach, enter the respiratory tract and reach the lungs. Normally, there are protective mechanisms to prevent aspiration, however, these mechanisms can be defective in patients who smoke or have lung disease. According to some present studies, aspiration does appear to be a mode of Legionella transmission. It would neither be safe nor correct to (so simply) state that "You can not get Legionnaires' disease from drinking water containing Legionella!" 10 Legionella 2003 -Update and A WT Statement IV. Domestic Plumbing (Potable Water) Systems & Legionnaires' Disease Legionnaires' disease is an environmental disease and an environmental issue, with safety and health responsibilities to be addressed by many. Legionella occur naturally in aquatic habitats and are routinely recovered from municipal water supplies. Low levels of Legionella in municipal water may seed industrial potable water, cooling water and process water networks. Legionella may colonize and amplify in hot water tanks, humidifiers, water- disseminating devices, cooling towers, ice machines, dead legs in distribution systems and other areas where microorganisms are able to flourish. Cooling towers captured a lot of initial attention and regard to being a significant (possible) reservoir of Legionella and LD health concern. Equal attention and regard, if not more so by some experts, is now appropriately given to the domestic (potable) hot and cold water plumbing system as a significant (possible) reservoir of Legionella and LD health concern. Evaporative cooling systems were initially implicated as the source of Legionella in nosocomial Legionellosis outbreaks. And early on, these systems and cooling towers in general became the "official source and reservoir" of Legionnaires' disease. This was unfortunate and proved problematic to cooling tower owners, manufacturers and to the water treatment industry as a whole, for they were subsequently expected to be the ones responsible to "take care or Legionella. Eventually, epidemiological investigations showed that potable water systems can be a significant source of Legionella. While the larger, headline-grabbing, LD outbreaks are usually associated with cooling towers, information from the United Kingdom (U.K.), Health and Safety Executive, shows that the vast majority of LD cases are sporadic and from sources other than cooling towers. As well, the Centers for Disease Control and Prevention indicate the vast majority of LD cases go unreported and undetected. In studies conducted by Hodgson and Casey in 1998, several thousand samples collected from a variety of sources showed: Legionella Colonization Frequencies: (Hodgson & Casey study, 1998) Iii!> Cooling Towers Iii!> Potable Water Distribution Systems Iii!> Hot Water Heaters 6.26% 7.01% 12.03% While water treatment specialists more typically deal with the non-potable water systems that they chemically treat, i.e., cooling towers, evaporative condensers and other heat~ transfer associated water systems, they should also be knowledgeable concerning· Legionella in domestic plumbing systems. The Domestic Plumbing System & Legionella: The domestic (potable) water plumbing system can harbor Legionella, provide Legionella with favorable growth and amplification conditions, and has many outlets (taps, shower heads, etc.) to disseminate aerosols that may transmit LD. These systems are an integral part of most buildings, commercial and otherwise, large complexes, including hospitals and other health care facilities, as well as industry in general. Plumbing systems were first implicated in a nosocomial (acquired during a hospital stay) case of Legionnaires' disease in 1980. Since then, plumbing systems have been associated with numerous outbreaks of LD. The United Kingdom reported 19 of 20 hospital LD outbreaks, from 1980 to 1992, to be from plumbing systems. 11 Legionella 2003 -Update and A WT Statement In addition, cases of LD have also been attributed to plumbing systems in nursing homes, workplaces, and private residences. Domestic plumbing systems are thus a major source of concern for LD contraction, particularly within the health-care industry. Hot-water systems are perfect breeding habitats for Legionella, as well as other bacteria that grow in biofilm. Legionella can flourish in hot-water tanks, especially in the bottom where warm zones develop beneath accumulated scale and sediment. The complexities of hot-water piping present an even greater problem than tanks alone. Biofilm and scale that form in valves, fittings and on pipe walls not only amplifies further bacterial growth, but also protects the bacteria "within" from hot water and chemical disinfectants. Deadlegs (unused piping) create additional problems because bacteria grow well in stagnant water conditions. Temperature is an Important Factor: Consider temperature in the proliferation (and control) of Legionella. Figure 2 illustrates several key temperatures for Legionel/a. The most important range to consider from the chart is the growth temperature range. Although growth has been recorded between 2ooc and 45°C (68°F and 113°F), the optimum amplification range is a narrower band of 30°C to 40°C (86°F to 104°F). Above 45°C {113°F) Legione/Ja is killed with time, and at 50°C (122°F) it may take up to two hours to attain a 90% kill. Below 20°C (68°F) Legionella is largely dormant, though some low level amplification may occur within the vacuole of the protozoan host organism. Figure 2: Legionella and Water Temperature Note: Figure 2 is courtesy of Southeastern Laboratories, Inc. Legionel/a training material presentations. The temperature data in Figure 2 certainly suggests that the operation of potable or domestic hot water systems be at temperatures as high as possible. However, practicality has to consider the risk of scalding injury and energy conservation requirements. 12 Legionella 2003 -Update and A WT Statement It should be emphasized that temperature data (as in figure 2) is usually based on laboratory studies and is not from actual system (piping) studies. As well, it must be emphasized that the system temperature is rarely one temperature {uniform) throughout the entire system. Thus, it should not be implied that maintaining potable water systems above sooc (122°F) guarantees Legionella control -practical experience has proven otherwise. In actual plumbing systems, especially the larger and/or more complex piping systems, Legion ella can survive at even higher temperatures due to biofilm, deadlegs, and other complexities. Accordingly, system temperature should not be relied upon for Legionella control (alone} without routine sampling also indicating control. Disinfection of Domestic Plumbing Systems: Public {municipal) water systems are required to be disinfected at their points of distribution to conform to existing federal standards for bacterial disinfection. However, the federal standards are based upon the absence of Coliform bacteria counts and do not include any specific testing requirements for Legionella. Following disinfection, municipal water supplies generally travel miles before points of use. During this course, disinfectant residuals diminish and there is increasing exposure to potentially biofilm-contaminated piping. Figure 3: Biofilm and Potable Water Distribution Systems Note: Figure 3 is courtesy of the Montana State University-Bozeman Center for Biofilm Engineering. 13 Legionella 2003 -Update and A WT Statement Treatment Technologies: There are a variety of methods used to disinfect potable water systems at their point of use. The following is a summary of those most commonly considered and an over view of their technology, as well as their associated advantages, disadvantages and current regulatory considerations. 1. Heat-and-flush (heat shock): This method is a thermal eradication process and involves raising hot water tank temperatures to greater than 140°F (60°C), preferably to greater than 150°F (66°C), and circulating (flushing) through all outlets for up to 30 minutes. The flush time required will depend on the temperature of the water when it reaches the outlets. !Iii> Summary: Thermal eradication provides temporary results; it is very labor-intensive, presents scalding risks, has associated high energy costs, is difficult to achieve complete effectiveness and, at best, provides only short-term (weeks to months) effectiveness. 2. Chlorination: For remedial or temporary disinfection, chlorine is added to water tanks at levels much higher (20-50 mg/1 free chlorine) than normal for potable water and flushed throughout the system. For continuous disinfection, flow-adjusted injectors are installed to release chlorine at a drinkable concentration (1-2 mg/1 free chlorine) throughout the domestic water system. However, it has been shown that Legionella suspended in chlorine demand-free water, pH 7.4, containing 2.5 mg/1 free chlorine can survive 10 minutes incubation (Gilpin, et al. 1985-see references). !Iii> Summary: Shock chlorination {high levels) provides temporary results, but is also very corrosive to copper and steel piping, produces potentially carcinogenic disinfection by- products {DBPs), ii"Jcluding trihalomethanes {THMs) and haloacetic acids, when reacted with organics, and provides short-term residual effect. !Iii> Summary: Continuous chlorination (1-2 ppm free) is minimally effective against biofilm, not proven highly effective on Legionella, and may pose corrosion, odor or taste problems. (Unacceptable taste and odor problems generally restrict its use above 2 mg/1. Chlorine, as C/2, is regulated under the EPA National Primary Drinking Water Regulations (NPDWRs) as a disinfectant at a maximum contaminant level (MCL) of 4 mg/1. Its recognized disinfection byproducts, total trihalomethanes and haloacetic acids are regulated at MCLs of 0. 10 and 0.060 mg/1 respectively.) 3. Ultraviolet (UV) Radiation: UV is a point-source disinfection method and no chemical residual is produced or carried throughout the system. Light in the ultraviolet (UV) spectrum range of 250 to 280 nm is microbiocidal due to its action on the nucleic acid structure of DNA. UV sterilizers (lamps) installed on water lines operate to kill Legionella as water flows through the unit. Sufficient energy and residence time are required to adequately irradiate the water column to an effective kill level. Suspended solids will scatter UV and dissipate UV energy. Scaling of the UV lens will interfere with light intensity and energy . .,.. Summary: UV systems provide point-of-use rapid kill and sterilization, they have no residual effect throughout the system or if unit is shut off and would not be effective in decontaminating systems already infested with Legionella and biofilm, they have energy cost and operational considerations and require clean ( <60 ppm suspended solids) water. 14 Legionella 2003 -Update and A WT Statement 4. Ozonation: Ozone is dissolved into the point of use water system to achieve a dose of about 1 to 2 ppm. Ideally, this is done with a generator that produces ozone in proportion to the water flow rather than a generator that produces ozone at a constant rate regardless of demand. Since ozone is a very strong oxidizer, it is an excellent microbiocide and proven effective at low concentrations. However, it can damage piping and since it has an extremely short half-life, it is virtually impossible to maintain any significant residual throughout a dynamic water system. ~ Summary: Ozone generation has significant equipment cost as well as maintenance and operational cost considerations, disinfectant residuals are difficult to distribute or achieve throughout the system and has minimal impact on biofilm or non-planktonic Legionella in dynamic or complex water systems. 5. Copper-silver ionization: Flow-through ionization chambers containing copper-silver electrodes are installed on hot-water lines. As electrical current is applied to the electrodes, positively charged copper and silver ions are released into the hot-water system. The combination of these two metals provides a significant synergism of antimicrobial activity. The positive ions bond to negative bacterial (cell wall) sites, disrupting membrane structures and lead to cellular death. Systems in which the water has scaling potential and/or pH levels above 8.0 are problematic due to scaling electrodes and precipitating copper-both of which lend to significantly reduced effectiveness. ~ Summary: Effective treatment with long-term residual effectiveness when off and has a relatively moderate yearly cost of treatment; however, initial capital expense is high and pH higher than 8.0 and scaling water may limit effectiveness and increase operational maintenance and cost; not used to treat the cold water supply, which can be a source of Legione/la amplification; local restrictions on copper and/or silver discharge may limit use or effectiveness and the potential for galvanic corrosion on steel exists. (Copperis regulated under the EPA NPDWRs as a contaminant at an MCL of 1.3 mg/1 with silver listed as a secondary (NSDWRs) contaminant at 0.10 mg/1.) 6. Chlorine Dioxide: Chlorine dioxide is a highly reactive gas that readily dissolves in water and remains a true gas in solution. It does not significantly hydrolyze in water, thus it retains biocidal activity over a broad pH range. Its primary mode of action is oxidation, however: a) it does not react with naturally occurring organic compounds to form THMs, b) is non-reactive with ammonia and most nitrogen-containing compounds, and c) is less aggressive to copper and steel than chlorine. It has viracidal and sporacidal activity and has been shown to be efficacious on Legionella, as well as effective in biofilm. For most practical water treatment disinfection purposes, it must be generated on-site for subsequent use. Prior to the newer electrochemical methodologies of generation today, on-site generation of chlorine dioxide was considered objectionable due to the necessity to intimately handle the hazardous chemical reactants. The packaged systems for chlorine dioxide production available today have eliminated this major objection. ~ Summary: Chlorine dioxide is an effective treatment for Legionel/a and biofilm at levels as low as 0.2 mg/1 with minimal objections; however, it must be generated on-site and treatment cost may be a consideration. (Chlorine dioxide, as CI02 , is regulated under EPA NPDWRs as a disinfectant at an MCL of 0.8 mg/1. Chlorite, a disinfection byproduct, is regulated at an MCL of 1.0 mg/1.) 15 Legionella 2003 -Update and A WT Statement Note on Monochloramine: The use of monochloramine as a biocide in municipal water systems has proven more effective than chlorine and is currently in use by 25% of municipalities. It is more stable than chlorine and produces fewer disinfection byproducts (DBPs). In addition, field epidemiologic data correlates well with reductions of Legionella in potable water systems treated with monochloramine (Chapter 79, ASM Press book on Legionella, 2002). (Chloramines, as C/2, are regulated as an EPA NPDWRs disinfectant at an MCL of 4 mg/1.) Note on EPA Drinking Water Standards: The National Primary Drinking Water Regulations (NPDWR) are legally enforceable standards that apply to public drinking water systems. These standards protect public health by limiting the levels of contaminants in drinking water. The National Secondary Drinking Water Regulations (NSDWR) are non- enforceable guidelines regulating contaminants that may cause cosmetic effects (such as skin or tooth discoloration) or aesthetic effects (such as taste, odor or color) in drinking water. The EPA recommends secondary standards to water systems, but does not require the systems to comply. State Departments of Environmental Resources (or Protection) are responsible to enforce the primary standards and may choose to adopt secondary standards as enforceable. The applicability of these standards to point of entry (POE) or point of use (POU) treatment technologies in non-public water systems (e.g., healthcare facilities using a municipal water supply) is an unresolved issue and should be considered when evaluating treatment options. At present, states are taking various approaches to non public drinking water distribution systems within facilities. These range from no involvement at all to full requirement of the use of products certified under ANSI standards. Some states require their non-public water systems applying treatment technologies to comply with a variety of regulations including permitting and other reporting requirements. These regulations do not apply to process, cooling towers, or other non-potable water systems. Facilities should certainly evaluate their state requirements when considering treatment technologies. Along with any disinfection methods of treatment used, the following are recommendations and sound practices to help manage and reduce the incidence of Legionella contamination within domestic plumbing (hot and cold) water systems: • Reduce deadlegs (stagnant lines and stubs) in the system, • Clean and inspect hot water tanks regularly-annually as a minimum, • Continually run hot water circulation pumps-avoid recycling to mixing valves only, • Store hot water at a minimum temperature of 60°C (140°F) and deliver to the taps at a minimum temperature of 50°C (122°F), • Store and distribute the cold domestic water below 20°C (68°F) -if not possible, then consider monitoring for Legionella and using a disinfection system if Legionella are not under control, • Flush the entire water system on a regular basis, • Consider routine potable water treatments -including the use of approved biocides. 16 Legionella 2003 -Update and A WT Statement V. Cooling Towers: Water Treatment & legionnaires' Disease Cooling towers and evaporative condensers have the potential to develop infectious concentrations of Legionel/a. These systems can provide the favorable conditions for the growth and amplification of many microorganisms, including Legionella. Tower drift (water loss) becomes the mist or aerosol that can transmit potentially infectious Legionella. The evaporative (cooling) process causes makeup waterborne constituents, as well as system water constituents, to concentrate (i.e., remain in the tower loop according to cycles of concentration). The recirculating water's retention (residence) time in the water loop allows for increased growth and reproduction of organisms. Warm water temperatures, along with the presence of corrosion by-products, other deposits and sediment debris, further promote biofilm and provide Legionella an ideal environment for growth and amplification. Water Chemistry & System Maintenance should be well controlled in these systems. The chemical treatment objectives of any prudent water treatment program are to reduce corrosion, deposits, and microbiological fouling. These same practices will also significantly contribute to the control of Legionella growth and amplification. Cooling tower systems associated with ineffective water treatment practices and/or neglect certainly present a greater likelihood of harboring potentially infectious Legione/la. However, high (even infectious) levels of Legionella have been found in otherwise well-maintained and operated tower systems. Testing performed on 1336 cooling tower samples from routinely maintained tower systems (Gilpin, et al., 1995) showed that Legionella was not found to be ubiquitous in such systems: 46% ofthe samples had no detectable Legionel/a, 90% of the samples had less than or equal to 200 morphologically intact Legionellalml and only 3% had counts exceeding 1000 morphologically intact Legionel/alml. Ill>-Biocide Treatments play a major role in microbiological control programs, including the control of Legionella. However, biocide treatments do not generally target specific microbial organisms, nor are they 100% efficacious. In the case of Legionella control, it must be stressed that the efficacy of any specific biocide can only be determined by testing for the presence of Legionella in the field under actual operating conditions. Environmental Legionella cannot be reproduced in the laboratory from culture-grown organisms. Therefore, laboratory trials should not be relied upon exclusively for proof of a biocide's efficacy against Legionella. In addition, Total Bacterial Counts (TBC) of a cooling water system should not be relied upon for any definitive correlation to Legione/la counts, control or disease risk. Legionnaires' disease has been associated with systems where the total bacterial count was very low, yet Legionel/a counts high. Systems have also been found to have very high total bacterial counts, yet very low and even zero Legionel/a counts. Ill>-Biodispersants play an important role in microbiological control programs, particularly against Legionella. These chemicals act to loosen microbial deposits (slime, sludges, etc.) and promote system cleanliness. Biodispersants promote biocide penetration of biofilm and enhance the effectiveness of biocides. Biofilm is often seen as the slime layer on surfaces in contact with water. Legionel/a flourish within biofilm since it is nutrient-rich and contains a diverse population of microbiota, including amoebae and other protozoa. As opposed to being freely suspended (planktonic) in the bulk water, biofilm Legionel/a and Legion ella within protozoa are protected from concentrations of biocide and/or other environmental conditions that would otherwise kill or inhibit them. 17 Legionella 2003 -Update and A WT Statement Biodispersants should not be used alone in microbiological or Legionella control programs without also using biocides. In their various modes of action, biodispersants may loosen and free large amounts of biofilm related bacteria (including Legionella) into the bulk water. These bacteria may be viable and (now in the bulk water) have the potential to be transmitted from the tower and pose an LD health risk. Biodispersants are meant to supplement and enhance the performance of biocides, not replace or serve as an alternate to the use of biocide. Cooling Tower Disinfection for the purpose of Legionefla control and disease prevention is generally recommended as: " Maintenance actions for startup, post lay-up or regularly scheduled tower cleaning; " Corrective prevention and control actions following system (tower) Legionella sampling with elevated counts; and " Required actions following a confirmed or suspected system LD case. The following is an abbreviation of the emergency cooling tower disinfection method described by the Centers for Disease Control and Prevention (CDC), 1997. This procedure is usually used if there is suspicion that the tower may have been the source of exposure for a case of Legionnaires' disease. The complete methodology should be previewed for a full understanding of the CDC procedure. It should be noted, however, that most cooling tower and water treatment experts differ with respect to the chlorine levels recommended and the routine frequency of using this type disinfection, due to the corrosive (damage) potential of chlorine to system materials of construction. Guidelines established by ASHRAE (2000) and by CTI (the Cooling Technology Institute) (1996) should also be consulted. 1. Shut off the cooling tower fans; 2. Keep makeup water valves open and the circulation pumps operating; 3. Close outdoor air intake vents located within 30 meters of the cooling tower; 4. Achieve an initial free residual chlorine (FRC) of at feast 50 mg/L; 5. Add a dispersant to tower water within 15 minutes of chlorine addition, then maintain 1 0 mg/L FRC for 24 hours; 6. Drain and refill the system, then repeat steps 4 and 5 at least once to remove all visible algae-like film; 7. Using a brush and water hose, thoroughly clean all water-contact areas, including the basin, sump, fill, spray nozzles, and fittings; 8. Circulate 10 mg/L FRC for one hour, then flush the system until free of all sediment; 9. Refill the system with clean water and return to service. Note: It is generally recommended today that dispersant-chlorination (only) disinfection procedures for Legionella also include a final step maximum dosing (per EPA label) of a nonoxidizing antimicrobial combination -either a synergistic combination in one product or two separately applied products. 18 Legionella 2003 -Update and A WT Statement VI. Cooling Towers and Legionella: Objectives and Guidelines Cooling Tower Legionella Objectives-Minimizing Counts & Transmission Because of the potential for any cooling tower to harbor, amplify and to disseminate Legionella, control measures need to be considered for all cooling tower and evaporative condenser operations. Legionel/a control measures should encompass two objectives: 1. Minimizing Legionella Counts in Cooling Towers: Practically keeping Legionella below detectable levels in every cooling tower system at all times is not feasible and should not be expected. However, practices and precautions to minimize Legionella in cooling towers are reasonable and should be an ongoing control effort. Many of the measures that are generally recommended for Legionella control in cooling towers are also recommended for the efficient operation and proper maintenance of a cooling tower system and include: • Proper Design • Periodic Cleaning • Regular Maintenance • Effective Water Treatment In combination, these measures generally minimize Legionella counts in a tower, but cannot be expected to eliminate them entirely in every system. Even properly maintained and operated cooling towers have been found to have high Legionel/a counts. 2. Minimizing Legionella Transmission from Cooling Towers to People: Minimizing transmission from the tower to a host is the second responsible measure in reducing risk of LD, again recognizing that there are no guarantees to keeping a tower system 1 00% Legionella-free. The following considerations should be made: • Minimize Tower Drift with proper and well maintained eliminators • Locate Tower to keep drift from air intake pathways to potential hosts • Locate Tower to keep outside sources of plant life or nutrients from entry • Use of appropriate masks or respirators by workers or others subject to drift Design Guidelines for Cooling Towers and Evaporative Condensers should take the following into consideration to minimize Legionel/a counts in the tower and minimize transmission of Legionella from tower to people: 1. Tower location should consider prevailing winds and proximities with respect to people populations (particularly at-risk populations), building air intakes and surrounding units. 2. Tower location should consider prevailing winds and proximities which could introduce bacterial nutrient sources into the tower (kitchen exhausts, industrial processes, etc.). 3. Shield or cover cold-water basins, distribution decking, and other wet surfaces from sunlight to prevent algae growth in biofilms. 4. Materials of construction should be smooth and non-porous. 5. Water distribution piping should: a) be as simple as possible -avoiding deadlegs, stagnant lines and loops that are difficult to drain, b) promote effective flow through the entire system-utilizing equalization lines when necessary. 6. Towers should be easily accessible for inspection, sampling, cleaning and disinfecting. 19 Legionella 2003 -Update and A WT Statement 7. The system should be designed to be completely drained or pumped out. 8. Provisions should be made to effectively dose, monitor and control a water treatment program, including: a) inhibitor and biocide/s chemical injection, b) water sampling, c) corrosion coupon sampling, and d) effective bleed and control points. 9. High efficiency drift eliminators should be used and maintained. 10. Filtered water, treated with trace (or greater) halogen residual, should be used as tower make-up. 11. Multiple-cell tower basins should be designed such that each cell and basin can be isolated, while the other cells remain in operation. 12. The tower system's total operating volume should be known for proper chemical dosing, particularly that of biocide and dispersant treatments. Figure 4 shows the physical and mechanical relationship of a cooling tower to its associated HVAC equipment and the potential transmission of Legionella within the system to an office or other facility building air supply. It should be clear from this graphic why many of the cooling tower design and operational recommendations are made with respect to Legionella control and minimizing the risks of LD transmission. Figure 4: HVAC and Legione/la Transmission f.tellscape ® fitfp:l.~medscape:com ( "' " "' "' ~ '" ~ ~"" " Note: Figure 4 is courtesy of Medscape® at http://www.medscape.com 20 Legionella 2003 -Update and A WT Statement Operational Guidelines for Cooling Towers and Evaporative Condensers should take the following into consideration to minimize Legionella counts in the tower and minimize transmission of Legionella from tower to people: 1. Clean tower and disinfect before start-up, especially new system start-up, and after any long shutdown period (greater than 2 to 4 weeks). 2. Treat water for control of corrosion, scale, fouling and microorganisms. 3. Establish a maintenance plan and log all activities, including the chemical treatment program's dosages, services and results. 4. Maintain all drift (mist) eliminators in efficient and proper operating condition as well as the operations of fans that affect drift productions. 5. If deadlegs in the piping system exist and cannot be removed, blow them down regularly -particularly after biocide treatments and cleanings. 6. Exercise all valves in the system periodically by opening and closing them fully. 7. Clean the basin when slime, algae, or dirt are visible. 8. Blow down direct free cooling (chilled water) risers weekly. 9. Thoroughly flush and clean the entire system at least once (preferably twice) a year- and include an oxidizing disinfection before and after each cleaning. 10. Where a cooling tower is out of use, it should be drained and kept dry. How Much Halogen? Many, including OSHA and CTI, recommend continuous feed of chlorine or bromine to effect control of Legionella in cooling tower systems. However, there is not a consensus recommendation on the (free) halogen level to maintain in these systems. The OSHA Technical Manual states that maintaining less than 1.0 mg/L free chlorine or bromine (with continuous feed) may not be enough to control Legionella, while more than 1 mg/L may be corrosive. CTI recommends 0.5 to 1.0 mg/L free halogen. A realistic approach would be to establish a free halogen level based on an evaluation of the "technical specifics" for each system, and include the following considerations: " System materials of construction and sensitivity to oxidant corrosion or attack, " Water chemistry (indices) and corrosion potential for the system, " Corrosion control history, if not new, for the system, • Corrosion monitoring program in place, • Microbiological and other fouling potential for the system (process or HVAC), • Microbiological control history, if not new, for the system, • Technical capabilities of the corrosion control productls (program), • Technical capabilities of the alternate microbiological control productls (program), and 21 Legionella 2003 -Update and A WT Statement • A Legionella risk assessment of the system to include: .,._ Design, maintenance & operation, .,._ Proximity of "at-risk" host populations, .,._ If Legionella testing is done, and .,._ History of Legionella control Accordingly: Systems where Legionella risk and/or history are great (bad) may opt for the higher free halogen levels (1-2 mg/L, or more), even if corrosion potential or failures may be higher than desirable. And: Systems with less tolerance for corrosion failures and having a low Legionella risk assessment would operate at the lower free halogen levels (0.5-1 mg/L). The ability to monitor corrosion and/or Legionel/a control provides additional tools to determine and "fine-tune" what free halogen levels work best to achieve treatment and protection objectives. Finally, if corrosion control is a must, yet unacceptable with the free halogen levels needed for Legionella control, then an alternative Legionella control program should be designed. Chlorine dioxide, a proven biocide effective against Legionella without posing the corrosion problems associated with halogen biocides, could be considered. Using multiple non- oxidizing biocides, along with biodispersants, at their maximum allowable dosages may be considered, although there is generally increased treatment costs associated with such programs. 22 Legionella 2003 -Update and A WT Statement VII. Sampling and Testing for Legionella: A Proactive Decision Legionella Testing -Logic: Sampling and testing for Legionella can be useful in helping assess risks and in determining whether or not preventive and corrective measures are working. Having an action plan based on results of Legionefla sampling can alert you to increased risks and whether or not disinfection procedures should be implemented. Not sampling tells you nothing about a system-until a case of LD occurs. With those quite logical and simple statements made, it may be assumed that Legionella sampling should be and is routine for any monitored system. Such is not the case. Legionella Testing -Issues: Legionella experts have debated the issue of routine sampling and testing for years. The CDC advocates sampling after LD has been found (suspected or confirmed) so as to locate the source of Legionella and take remedial action. They do not encourage sampling in the absence of suspected or confirmed LD cases. Other experts disagree with this and advocate a more proactive approach of conducting periodic sampling (so-called "routine sampling") even if no cases of LD have been detected or suspected. Some of the current facts and understanding of Legionel/a and LD that continue to support any real consensus from being achieved amongst the experts include the following: • There is no specific infectious density known for Legionella or a clearly established correlation between test culture or direct fluorescent antibody (DFA) test results of Legionel/a and risk of contamination. • Legionella is frequently present in water supplies without causing disease, so routine testing and obtaining positive test results do not mean LD will occur. It may even produce a false sense of alarm and lead to costly corrective actions being undertaken. On the other hand,·obtaining negative results does not assure that LD cannot occur and may provide a false sense of security that leads to relaxation of prevention measures. J. Brown (et al., 2001) noted that Australia has a protocol requirement for immediate cooling tower decontamination when Legionel/a counts reach a certain level. However, towers directly linked to LD cases were found to have Legionella counts below the protocol action level. • Interpretation of results in routine Legionella sampling is still questionable due to: .,.. Different bacteriologic methods used amongst laboratories, .,.. Variable results between culture and direct fluorescent antibody methods, .,.. Variable culture results from differing sites within the same system, and .,.. Variations in the counts of Legionella isolated from a single site. In addition, potentially infectious Legionella in some water samples may not grow on the microbiological medium specifically formulated to grow Legionella. • The risk of illness following exposure to a given Legionella source is influenced by a number of variables and factors other than just the concentration of organisms in a sample. Host susceptibility, Legionella strain virulence, and efficiency of Legionella transmission (to host) are integral to LD risks and disease progress. 23 Legionella 2003 -Update and A WT Statement "' Routine testing may present ambiguous (legal} liability issues: testing and getting positive results may establish a legal liability if a disease case occurs; yet the testing may prevent negligence charges from applying. On the other hand, not testing in the face of risk or other factors may support negligence and guilt in defending a responsible LD case. (Cases to note: In 1997 OSHA fined a Cincinnati, OH injection molding facility following an investigation of three LD cases with no deaths. The fine was based on the General Duty Clause that requires employers to maintain a workplace free from recognized hazards. However, in 1998, following an investigation of LD cases with a death at a Baltimore, MD injection molding facility, the Maryland Department of Occupational Safety and Health Administration (MOSH) did not fine the employer. In the Maryland case, it was decided that plant management had taken proactive steps to reduce risk of LD among employees. The Maryland company had a good water treatment program and took immediate action to reduce the possibility of more cases of Legionnaires' disease.} Legionella Testing is a Proactive Choice: There is no risk for LD if there is no Legionella. The only (practical) way to know if you have Legione/la is to test for it. Since the risk of LD depends upon Legione/la being present, those in favor of routine sampling maintain testing is logical, necessary and a proactive choice. The same reasoning applies, that, if you are taking measures to minimize Legionella in water, then you should periodically check Legionel/a levels to be sure that preventive measures are working. Although sometimes inconclusive, the results of sampling can at other times provide life-saving information. Most experts do agree, including those that do not favor routine sampling, that there should be a consideration to sample any system that presents significant LD risk and/or exposure potential. Final consideration would be based on a thorough review and risk assessment of the system and its operating particulars. Specific risk assessment data would include: makeup and system water characteristics, system design and operational data, fouling history and potential, potential host populations and susceptibility, and LD case history. Legionella Sampling: The most important consideration in Legionella sampling (testing) is to select a laboratory that has significant experience in culturing and testing samples for Legionel/a. There are specific sample collection procedures, preparation criteria and shipping requirements that should be followed and will be provided by a competent testing firm. They are beyond the scope of this document but, in general, include instructions for: sample type (swab or water), sample size and container requirements, sterile collection (chlorine neutralization) procedures, un-refrigerated shipping and time requirements, etc. Legionella Test Results, Interpretations & Action Plans: The following excerpt is by J. R. Watson, Ph.D., Legionella Update-2000, Microbiological Consultation Services, Inc.: "Although small numbers of Legionella bacteria probably pose a very low risk to healthy individuals, corrective action should be kept in mind whenever legionellae are isolated from a water sample. Although the scientific community cannot agree on what number of Legionella bacteria is acceptable, we believe colony counts, as expressed in colony forming units (cfu) per ml of water, can be used as a loose guide for deciding when to implement corrective action. Legionella pneumophila colony counts for cooling tower specimens may be interpreted as follows: 24 Legionella 2003-Update and A WT Statement • >1 00 cfu/ml = large number of Legionefla bacteria. • 10-100 cfu/ml = moderate number of Legionella bacteria. • <1 0 cfu/ml = small number of Legionella bacteria." The significance of Legionella laboratory test results and subsequent formulation of action plans to apply to systems monitored for Legionella is still somewhat at question. Again, this is where the scientific community simply does not yet have a definitive consensus. However, there is a general consensus that some sort of guideline should be used versus none at all. The following various guidelines and action plans are provided as a resource to such an end: 1. The OSHA Technical Manual offers the following guidelines to use when interpreting Legione/la analyses for cooling tower and potable water systems. The guidelines may be used to assess the effectiveness of water system maintenance and Legionella control. These guidelines are based on limited data and are subject to change. They are intended to apply only to water systems being used by healthy individuals and are not necessarily protective for persons who are immunocompromised. The levels requiring action vary for the source of exposure based on the assumption that some routes or exposure result in a greater dose to the lung. For this reason, humidifiers and similar devices such as misters and evaporative condensers, which produce an aerosol mist that can be directly inhaled, should be controlled to lower levels. Remember that these numbers are only guidelines, and the goal is zero detectable Legionella in a water source. Levels of Legionella equal to or greater than the values in the table constitute a need for action, as described below . ..,. Action 1: Prompt cleaning and/or biocide treatment of the system . ..,. Action 2: Immediate cleaning and/or biocide treatment. Take prompt steps to prevent employee exposure. Colony Forming Units {CFU) of Legionel/a per milliliter Action Cooling tower Domestic water Humidifier 1 2 100 1,000 10 100 1 10 [From OSHA Technical Manual (Section Ill: Chapter 7, legionnaire~' Disease), which was adapted from George K. Morris, PhD, and Brian G. Shelton, Pathcon Technical Bulletin 1.3, Legionella in Environmental Samples: Hazard Analysis and Suggested Remedial Actions, June 1991] 2. Richard W. Gilpin, Ph.D., and GTS Legionella Water Testing Lab provides the following remedial action criteria as an attachment to all their Legionella test reports. The units of measure are from their Direct Florescent Antibody (DFA) epifluorescence microscopy and represent total numbers of morphologically intact Legionella observed . ._ <1 0-20/ml: This is the most common test result and does not require remedial action. Retest in a month to check for evidence of increasing numbers of Legionella. 25 Legionella 2003 -Update and A WT Statement ~ 30-190/ml: This is the second most common test result. A decision to disinfect the tower should be made by considering the numbers of Legionel/a, location of the tower, and the type of employee, patient, or visitor population. The tower's proximity to pedestrian traffic, building air intakes, open windows and doors should also be considered. If tower is disinfected, retest after disinfection to make sure the procedure was successful. Review and revise the biocide treatment program currently in use. If the tower is not disinfected, retest within a few weeks to check for evidence of increasing numbers of Legionella. ~ 200-1 ,000+/ml: Least likely test result, but may be reached quickly from a previously lower level. Result represents a public health concern and disinfection of the tower is indicated. If the count is >1 ,000/ml, take immediate action. Retest after disinfection to make sure the procedure was successful. Review and revise the biocide treatment program currently in use. Retest within a few weeks to check for evidence of increasing numbers of Legionella. 3. A common cooling tower Legionella testing and action plan is seen in Figure 5. It represents a composite compilation of various AWT member Water Treatment Company Legionella action plans for cooling tower operations. The frequency of tower sampling for Legionella varies widely amongst the programs (i.e., monthly, quarterly, semi-annually to annually) and is generally determined from specific site and system LD risk assessments. Figure 5: General Cooling Tower Legionella Testing Action Plan Note: Figure 5 is courtesy of Southeastern Laboratories, Inc. Legionella training material presentations. VIII. Health Care Facilities -A Special LD Risk Environment 26 Legionella 2003-Update and A WT Statement 84 68% 15 60% 69 Marrie 39 Liu 17 12% Note: Table 1 was excerpted and adapted from "Resolving the Controversy on Environmental Cultures for Legione/la: A Modest Proposal" by Victor L. Yu. Infect Control Hosp Epidemiol1998;19:893-897. Cooling tower samples are not included in the data. Health Care Facilities and JCAHO: Potable water plumbing systems present a favorable habitat for Legionella and pose an associated LD risk to the susceptible host populations within the healthcare community. Thus, there is a major emphasis on the risk assessment, control and management of these systems and their associated water disseminating equipment or systems in health care facilities. In accordance with this concern, the Joint Commission for the Accreditation of Healthcare Organizations (JCAHO) issued a new standard that became effective January 1, 2001. This standard, numbered EC 1. 7, requires all JCAHO accredited facilities to have a management program to "reduce the potential for organizational-acquired illness... It holds the health care facility responsible for "managing pathogenic biological agents in cooling towers, domestic hot water, and other aerosolizing water systems" -i.e., Legionella among others. The American Society for Healthcare Engineering (ASHE) has recommended in their technical reports on managing waterborne pathogens, per JCAHO EC 1.7, that health care facilities conduct a risk assessment of their potential sources of Legionella and develop a management plan for maintenance and operation of their water systems. 27 Legionella 2003 -Update and A WT Statement Health Care Facility-Risk Assessment & Management Plans: JCAHO surveyors now clearly expect health care facility managers to have a risk assessment and management plan in place to comply with JCAHO's EC 1.7 standard. Following is an outline from the ASHE web site on what a facility manager should be doing to comply with EC 1. 7 and what JCAHO inspectors are looking for: Step 1: Risk Assessment ~ Work with the Infection Control Practitioner to assess the clinical risk of the patient population to identify and review: • The treatment and care areas for patients at greatest risk, • Any cases or current history of infections resulting from water borne pathogens, including legionellosis. ~ Assess the environmental risk from potential amplification factors such as: • Domestic hot water systems • Design (i.e. dead legs and low flow conditions) • Operation (i.e. water temperature) • Maintenance (i.e. flushing and cleaning of hot water tanks) ~Assess cooling and humidifying systems, which produce aerosols: • Design (i.e. drift eliminators) • Operation (i.e. sterile water in room humidifiers) • Maintenance (i.e. cleaning cooling towers and use of an effective biocide) Step 2: Risk Mitigation ~ If susceptible patients are identified, work with the Infection Control Practitioner to determine what aerosolizing systems are present in that patient's environment (i.e. showers) and limit their access to these systems. Step 3: Operational Management of Risk ~ Develop a management plan as a result of the assessment (step 1) that includes standard operating procedures (SOP's) for maintenance and operation of water systems. ~ Develop a system to document and log findings as a result of these SOP's such as temperatures, blow down of hot water tanks, cooling tower inspections, etc. ~ Include in these SOP's a maintenance and audit program for any systems that are currently installed to limit Legionella amplification in aerosolizing systems such as cooling towers and/or potable water treatment systems (e.g. copper-silver or chlorine dioxide). ~ Inspect cooling towers/evaporative coolers to ensure that they are in proper condition and operate as designed. Step 4: Remediation (if required) ~ Work with the organization based Infection Control and Safety committee to establish a contingency plan for water system decontamination to be implemented if Infection Control identifies an outbreak of Legionellosis and corrective steps are needed. 28 Legionella 2003 -Update and A WT Statement IX.

AWT Position Statement-Legionella & legionellosis The Association of Water Technologies makes the following recognition and position statements regarding Legionnaires' disease, water treatment and related practices of water treatment specialists. They are based on the significant and prevailing information from ASHRAE, CDC, CTI, EPA, OSHA, the medical community, leading experts and other authoritative agencies that study, investigate and deal with Legionella and Legionellosis. 1. AWT recognizes the potential hazard for Legionella contamination in cooling towers and evaporative condensers, as well as other water systems and water disseminating devices or equipment that may or may not be a part of water treatment programs. 2. A WT supports that prudent operational and water treatment practices for cooling towers, evaporative condensers and other recirculating water systems, are consistent with reducing Legionella contamination within them and include: • Corrosion, scale and deposit control programs that promote operational efficiency and system cleanliness and reduce microorganism-breeding areas. • Dispersant, biodispersant and antifoulant programs that reduce biofilm, sludge, debris and dirt accumulations-that further reduce microorganism-breeding areas. • Biocide programs, including oxidizing and non-oxidizing treatments that are applied according to proper labeling, to control microbiological growth· and proliferation. • Maintaining best available mist elimination technology in evaporative systems and eliminating or minimizing stagnant (dead-leg) zones and areas. • A minimum annual (twice annual preferred) thorough wash-out and cleaning of cooling towers and evaporative condenser cooling water systems -including an oxidizing disinfection before and after each cleaning. 3. AWT supports that the microbiology and environmental ecology of Legionella includes many variables that determine organism virulence and survival, disease transmission and contraction, and human host susceptibility. And, even prudently applied water treatment programs cannot guarantee 100% Legionefla eradication or disease prevention. · 4. AWT supports the sampling and testing for Legionella in cooling towers, evaporative condensers and other water systems appropriately risk-assessed and evaluated to pose disease risk. Specifically targeted systems include those that have a likelihood of harboring Legione/la and/or pose an increased risk of transmission to populations of at-risk hosts. Monitoring for Legionella within a facility may also be appropriate or required to: • Verify the effectiveness of water treatment protocols, • Evaluate potential LD transmission sources, • Verify the effectiveness of Legionella decontamination procedures, • Test within certain healthcare facilities that have patients at high risk for LD. 30 Legionella 2003 -Update and A WT Statement 5. AWT supports that Legionellq sampling and testing should be considered for all potential Legionella-source water systems. An ultimate decision to test or not should be determined and based upon an assessment and review of the specific water system (site and operations) for LD risks. This includes having an understanding of relevant facts on Legionella sampling and testing, Legionel/a and Legionnaires' disease, and having an action plan for test results. Accordingly, AWT does not recommend the routine sampling and testing of all systems without appropriate assessments. 6. AWT will continue to investigate and evaluate, as well as promote and report, the latest findings, research and technologies relevant to the control of Legionella and the prevention of Legionnaires' disease. This includes independent research, as well as liaison and joint exchanges with government agencies, other organizations, associations, and related professional entities. 7. AWT, as a Responsible Care® Partner Association, further commits to sharing with the water treatment industry, the health care community and industry at large, as well as the general public, any relevant information gathered and produced from their resources addressing Legionella and Legionellosis. 31 Legionella 2003 -Update and A WT Statement References American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE), Atlanta, GA.

Customer RePJ11sentatlve PACH,P, Inc. Representetlve CHAPTER 14 HOV¥ TO PRE-CLEAN NErV BOILERS PREFACE The primary objective of pre-cleaning for industrial boilers is usually to remove the oil and grease from fabrication and! or erection. The technique used is very simple. old and effective -- produce a highly alkaline environment with either soda or caustic and mix that with phosphate (usually trisodium phosphate) and a small amount ofswfactant. The alkalinity breaks up the oil, the surfactant disperses it, and the phosphate acts as an absorbent. Of course, heat is necessary for effective results with minimal pressure of20 psig needed. Pre-cleaning to the utility usually means alkaline boil-out followed by an acid cleaRing to remove mill scale. Because the u.nits are operated at higher pressures where d(fferent corrosion mechanisms are at work. the removal oflhe FezOJ is necessary. Certainly. if the industrial boiler is going to be operated at high pressure or has unusual make-up wmer or boiler design characteristics. then the utility-type procedure may be advisable. My last boiler pre-cleaning experience occurred at a new aluminum smelter/refinery complex. The last of three new B & W boilers had been charged with chemicals and the author proceeded to wait six days before they could open it up to determine if the desired results were obrained. Plant start-up problems diverted management's attention and there we sat wailing an extra three days (usually boil-out time is 48-72 hours). This unfortunately is not uncommon, as things just don't go like clocl..•·.;ork during new plant stan-ups. Remember the objective of this procedure is to remove oil and grease, not mill scale for industrial boilers. GENERAL Before a new boiler is put into service, internal surfaces and waterwalls should be cleansed of foreign matter, such as lubricants or temporary protective coatings, that may have been used during fabrication or erection. This cleansing or "boiling out," as it generally is called, is an operation carried on under controHcd conditions as described hereafter. Also, it is important that the boiler setting be dried properly. The time required for drying out will depend primarily upon the amount of refractory, type of refractory, pcrcent.age of cast.able material used, the amount of moisture contained, and the elapsed time from completion of construction to the time of initial operation. Furnaces with little or no water-cooling provisions (refractory furnaces) may require up to 6 days in which to dry enough to avoid damage from high temperatures. If the furnace is completely water-cooled, the time required for boiling out usually is aU that is necessary for satisfactory drying of the refractory materials. The boiling- out operation used for cleansing may be done toward the end of the allotted time. Oil-fired furnaces equipped with air-heater bypass or recirculating duct should be operated with these in use, so as to maintain exit gas at as high a temperature as possible. The excess 118 air should be kept as low as possible without producing poor combustion in the furnace. Accumulations of soot or unburned oil on the air preheater and breeching should be kept to a minimum. Combustion conditions should be watched 10 guard against fl~e impingement or poor atomization. Units equipped with suiLable oil or gas- firing equipment may be heated by one or more torches (or burners) near the bottom of the furnace, depending upon the size of the unit. It is desirable to fire these burners alternately, where possible, so as to distribute the heat evenly. If oil is used, a No. 2 fuel oil is recommended. In the absence of other means, a wood fire built in the ash pit or on improvised grates supported on the water- screen tubes for hopper-bottom furnaces will be satisfactory. It is most important that the water used both for making-up the cleaning solution and that used to fill the boiler be compatible with the total system melallurgy. All parts of the system should be checked for materials of construction. Any parts or sections of stain- less steel, such as valve trim, superheater tubes, etc., should be protected from exposure to chlorides to prevent stress corrosion crack- ing when heat is applied. These parts should be isolated from the cleaning solution if it is 55-gal. drum Motor-driven mixer (preierred if available) Locate drum on a suitable platform above boiler drum or on ground with pump or eductor.

These precautions should include the water used for hydrostatic testing. It may be necessary to rinse out any in- compatible water used in hydrostatic testing before proceeding with the cleaning step wiili its application of heat PROCEDURE FOR BOILING OUT Clear the boiler for firing by taking the usual precautions that the boiler and setting are clear of men and tools. Check the tubes for 119 obstructions, fill the boiler with water, and leak test. It should be detennined that the water- feeding and level-indicating apparatus is in proper operating condition, and that the operators are familiar v,rith the necessary firing precautions. In high-pressure units where flat gauge glasses are used. usually it is desirable to install a temporat-y round gauge glass for boiling OUL The solution used for boiling out is composed of: Procedures of Indu.striall-Vater Treatment Commercial/ Anh''drous 42 lb-34 lb 42 lb -34 lb 8 lb-6 1/2 1b 7 lb-7 Ib Chemical Soda ash Trisodium phosphate Sodium nirrate Surfactant for each 1000 gallons of water held by the boiler and watenvalls. The necessary quantity of chemicals prescribed above should be dissolved in warm water, using at least 2 gallons of water per pound of chemicals. Provide a temporary dissolving tank, elevated at least 6 inches above the steam drum, for introducing the dissolved chemicals through an open manhole in the steam drum. Figure 14-1 is the minimum arrangement. All chemicals must be in solution when charged into the boiler to prevent localized precipitation and inadequate cleansing. Gloves, goggles, and a dust respirator should be worn when handling the trisodium phosphate and soda ash. The surfactant liquid must be diluted before charging, but must be agitated gently to avoid excessive foaming. After all the chemicals have been added, the drum manholes shall be replaced and the water level raised to approximately the center of the gauge glass. Open the drum vent valve. If the boiler is equipped with a superheater, the inlet-header drain and the drum vent should be closed and the drain or vent on the superheater outlet opened. Where an economizer is located above the level of the steam drum, it is not possible to provide for recirculation of chemically treated wash water from the boiler without the use of circulating pumps. Even with the economizer below the level of Ll}e steam drum, natural circulation cannot necessarily be assured. For these reasons, it is recommended that the economizer be flushed out with clean water, drained if feasible, and left empty during the boiling-out operation. (Limit temperature to economizer to 800 • F.) To get feedwatcr in(O the boiler, make a temporary connection to some other nozzle on the steam drum. These comments assume the economizer is a separate element of the boiler, which usually is the case with present day boilers. With the vent open, a slow fire should be started to heat up the unit gradually. If a long drying-out period is required, a very low firing 120 rate must be maintained for several days. Meanwhile, the water level should not be permitted to fall below normal and no steam pressure should be generated. It is desirable to install a thermocouple in the gas pass leaving the furnace. The thermocouple must be shielded from the radiant heat of the fire or burners so that a true gas temperature is obtained. The temperature rise of this gas should not exceed 100" F per hour and should not exceed 500" F during the drying-out operation. A strong flow of steam from the vent is required to produce needed circulation of boil- out solution. The flow should be approx- imately 2 percent of boiler capacity rating. When ready for boiling out.. the firing rate should be increased to bring the boiler pressure up to 50 percent of the normal operating pressure, at a rate not to exceed 50 psi per hour. This pressure should be held for a minimum of 24 hours for water tube boilers. A shorter boil-out may be used for rrre tube units. The iemperature of the bottom headers should be observed for indication of good circulation in order to be sure all parts of the unit have been boiled out. Actual measurement of the temperature is not always necessary as the smoking of oil on the handhole yokes, or similar indications, usually are sufficient. The boiler should be blown down successively to remove the foreign matter which the chemicals loosen. In some cases, fires must be extinguished periodically to control pressure; the blowdowns can be made during these off periods. The first blow down should be undertaken when the pressure has reached half of the desired boiling-out pressure. From then on, a quantity of from 1/4 to 1/2 gauge glass should be blown at four-to eight- hour intervals, alternating with each of the mud-drum valves, etc. No further chemicals need be added when refilling the boiler with water after blowdowns. After this, the flre should be extinguished and the unit allowed to cool gradually. If normal feedwater is available, several successive blowdowns may be made at intervals of 1/2 to 1 hour. Access doors and inspection doors should be kept closed until entry i..'lto the unit is desired. \Vhen cool, the unit should be drained (with drum vent open) and the manholes opened. The drums should be inspected for foreign matter remaining. Any sludge or scum should be wiped out immediately and the unit washed down with a minimum 1 1/2-inch pressure hose. Several handhole plates then should be removed at the bottom of the waterwail headers, the headers inspected, and flushed out with a hose. This should be done with care to avoid wetting of the setting. If possible, the refractory setting, baffles, floor tile, castable material, etc., should be checked after the drying-out period for cracks or excessive shrinkage. The boiling- out process should be repeated if necesgmy. If solid adhering scale is present after the second boiling out, cleaning with acid or high- pressure water may be required. Gaskets of all handholes and manholes which have been opened or show evidence of leaking should be replaced. 121 Preclean New Boilers Since gauge glasses may be damaged during the boiling out, they should be in - spected afterward and renewed when necessary. Remove temporary glasses if they were used. The unit then can be closed up and refilled with treated water to the recommended water level. A hydrostatic test should be made prior to placing the boiler in service. All refuse should be removed from the furnace before the boiler is put into service. If the boiler is not to be placed in service immediately, it should be laid up properly. (Refer to Chapter 16). LATTNER BOILER COMPANY 1 New Boiler Boil-Out Recommendations New Lattner Boiler Boil-Out Recommendations With proper operation and maintenance you can expect years of trouble free service from your new Lattner boiler. The procedure for correct operation and care of your unit is not complicated, nor is it time consuming. In this bulletin, we outline the proper boil-out procedure for you boiler prior to placing it into service. If is necessary to clean the inside of the new boiler of oil and grease used as tube rolling lubricants, threading, and/or other various reasons beyond the manufacturer's control. Since these coatings may lower the heat transfer rate of the heating surfaces, failure to remove these coatings will result in your unit foaming, priming, carry-over or other damage. The boil-out operation is easily accomplished by following the procedure as outlined below: 1. Fill the boiler to the normal water line. 2. Close boiler steam stop valve in the steam line. 3. Remove safety valves at the top of the boiler. The safety valves must be removed to prevent any contaminants or boil-out solution from entering them. 4. Tri-sodium phosphate and caustic soda each in the amount of one pound per 50 gallons of water are the suggested chemicals for cleaning boilers. Dissolve these compounds in water and add dissolved chemicals through an opening at the top of the boiler. 5. NOTE: When dissolving and mixing the boil-out chemicals, the use of a suitable face mask, goggles, rubber gloves, and protective clothing is mandatory. DO NOT permit the dry chemicals or the concentrated solution to come in contact with skin or clothing. 6. It is necessary to connect an overflow pipe from the safety valve opening in the boiler to a safe point of discharge. 7. After adding the boil-out solution, add water to the boiler until it is completely filled. 8. Fire the boiler intermittently at low fire for 4 to 5 hours. Maintain just enough heat to hold the solution at the boiling point. Be patient. IT IS CRITICAL THAT YOU DO NOT OVER FIRE BOILER DURING THIS PORTION OF THE START-UP. Do not allow boiler to produce any steam pressure. During this procedure, allow just a small amount of water to enter the boiler to carry off any surface impurities through the overflow pipe. 9. Continue the process until the overflow water appears clear. 10. Stop the burner and allow the water to cool to about 120°F. Drain the boiler while the water is still warm. 11. NOTE: Prior to draining the boiler, check with local water treatment facilities to determine whether special instructions or permits are required to dispose of the water. 12. Remove the handhole (and manhole) plates from the boiler and wash the interior with tap water at full pressure through a nozzle. Wash until all evidence of dirt, mud, and impurities are removed through the bottom handhole openings. 13. Inspect the internal surfaces. If not clean, repeat the boil-out procedure.

After closing the openings and reinstalling the safety valves, fill the boiler to its normal water level and fire it until the water temperature is at least 180°F to drive off any dissolves gasses and oxygen which might otherwise corrode the metal. On a steam system, the condensate should be wasted until test show the elimination of undesirable impurities. During the period the condensate is wasted, attention must be given to the treatment of the raw water used as make up so that an accumulation of unwanted materials or corrosion does not occur. Follow the advice of you water treating company. On a hot water system, chemical cleaning of the entire system is generally necessary and the entire system should be drained after treatment. Consult a water treatment company for recommendations, cleaning compounds, and applicable procedures.

The information presented is specific for open recirculating cooling systems and closed chilled water loops (it is not intended as a reference for other system types). This material was contributed by a number of individuals, thereby providing a consensus of opinion from differing regions, perspectives and operations. The corrosion rates and comparative grading are separated into two general categories: industrial process cooling and comfort cooling (HVAC) applications, so as to provide a more accurate reflection of performance relative to operational challenges. The document provides "Recommendations and Guidelines" for the water treater. This is not presented, nor is it proposed, as a Standard. It is intended to be used as an aid, in conjunction with other survey methods and data, to determine how well the metallurgies of a system are protected against corrosion and to gauge the impact of changes made to a water treatment program. This is a "living document" and will be expanded in scope, as more information is forwarded to, and reviewed by, the Coupon Task Group. Warnings and Disclaimers: This document is designed to provide information regarding the subject matter presented. It is produced with the understanding that neither A WT nor the contributors are rendering legal, medical, engineering or other professional services. Neither AWT nor the contributors shall be liable for damages, in any event, for incidental or consequential damages caused, or alleged to be caused, directly or indirectly, by the use of any information disclosed in this document, including the use of any recommendations, methods, products, services, instructions or ideas. ASSOCIATION OF WATER TECHNOLOGIES AWT Recommendations and Guidelines for Corrosion Coupons in Cooling Systems A corrosion coupon survey should have a defined objective prior to initiating the study. This helps to position the results and pursue any needed corrective action(s ). Corrosion coupons are useful in determining average loss rates over the installation period and can illustrate evidence of localized attack. The results identify trends that reflect acceptable corrosion protection, gains made by changes to the treatment program, equipment or operation of the system or the need for improvements that should be investigated by further survey work. Coupon studies comprise only one of a number of tools that are available to determine corrosion control. Each result needs to be viewed as a unique value for the operating conditions present during the survey period. This value should be compared against other results to identify improvements in control and protection. Corrosion coupon results are not an absolute reflection of actual system corrosion rates - existing oxides on older waterside surfaces typically retard corrosion more effectively than the protective surface developed on the corrosion coupon during the survey period. A poor rate does not necessarily reflect a significant problem; however, it does help to identify the need for corrective action. The values obtained from the gravimetric evaluation of corrosion using coupons, depends upon many factors. These factors include but are not limited to: 1. Type of industry 2. Exposure time in a water system coupon test rack 3. Coupon rack design and coupon placement 4. Orientation of the coupon 5. Flow characteristics passing over the coupon: water velocity, downtime, etc. 6. Temperature of the water passing through the corrosion rack 7. Water chemistry and quality 8. Process contamination: organics, gases, acids, alkalis, metals, etc. 9. Quality and concentration of the water treatment program 1. Acceptable values from an HVAC system (i.e. a cooling tower operating in an institutional or commercial facility) may not be attainable in a refinery, chemical or other industrial manufacturing plant. The same can be said for HVAC systems operating with a stressed water supply (i.e. make-up waters high in total dissolved solids, sulfates and/ or chlorides, as examples). Corrosion rates identified in these systems may not match the values used to evaluate protection in unstressed supplies. It might be more appropriate to reference the guidelines identified for industrial cooling tower circuits to gauge corrosion control when operating with these more difficult sources. 2 2. Corrosion rates measured by corrosion coupons are the result of time averaging the loss of metal from the coupon. However, the rate of loss of metal by corrosion of a clean, unpassivated coupon is not linear. Corrosion rates are much higher in the initial few hours or days of exposure. The higher rate of corrosion occurs during and until the metal surface acquires passivation. Therefore, a recommended and widely accepted exposure time for unpassivated corrosion coupons in a test rack is a minimum of 90 days. Short-term durations (30-days or less) usually will result in higher observed corrosion rates. The higher rates are the result of the short time averaging over the higher corrosion rates present during initial passivation. The short term and resulting higher corrosion rates may be justified when changes to treatment programs, or new treatment programs are being evaluated. With longer term duration, the initial high metal loss from the coupon becomes a smaller percentage of the overall weight loss. Also, as the metal coupon corrodes, the corrosion products can act as a barrier reducing the rate of further attack. 3. The corrosion coupon rack should be constructed of materials which will neither contribute to corrosion nor result in corrosion inhibition. Optimal placement of the rack would be on the return header to the cooling tower, or the return line from a chiller or heat exchanger (i.e. the site offering the warmest recirculating water). The effluent from the rack can flow back to the main water source in free flow to atmospheric pressure where the flow rate can be manually measured or return to the pressurized piping system where a flow meter is first used to monitor and control desired water flow rates. There is a wide range of opinions concerning preferred and acceptable materials of construction (M.O.C.) used in the manufacture of coupon racks. These vary from the more commonly applied mild steel, to stainless steel, PVC, galvanized and copper metallurgies. While successful applications of each of the common options have been noted there remain a variety of philosophies on the positive and negative aspects of each. Some of these philosophies are shown below. M.O.C. Pros Cons Carbon .. Suitable for higher pressure I .. Under severe operating Steel high temperature conditions the waterside • Rugged construction surfaces will corrode (but .. Components are readily that, in and of itself, would available identify poor control) .. Representative of the bulk of ..

Alkaline programs may attack than will carbon steel the galvanized pipe. (although this may mask an obvious corrosion concern) Copper • Suitable for higher pressure I .. Corrosion of the coupon rack Tube higher temperature components could adversely applications impact the corrosion results .. Sturdy construction ofless noble metal coupons (however, corrosion of the copper rack would also imply that corrosion of the system copper metal was occurring). Construction materials can be%" or 1' inch diameter, schedule 40 or schedule 80 piping. Temperatures of the water and pressure in the system must be considered when selecting the M.O.C. All required valves, strainers and flow restricting devices should be made of similar materials. Coupon rack designs are often promoted with horizontal sections that are no less than twelve (12) inches in length and vertical section lengths of three (3) inches, or more. When considering that all flows in excess of one (1) gallon per minute will be turbulent, increased horizontal pipe lengths beyond six (6) inches and increased vertical separations of the horizontal sections are unlikely to reduce turbulent effects (see Table 1 below). Comparative surveys should always be completed in the same coupon rack or coupon rack design as this will limit the variables associated to the differences in loss rates. It is commonly recommended that coupons should be placed into the corrosion coupon _ rack following the galvanic series in seawater. This stipulates that the most "active" or least "noble" metal or alloy must be placed in the number one position, which is the first coupon exposed to the flowing water. Other coupons would follow the galvanic series in seawater 4 with the last coupon being the least "active" or most "noble" metal or alloy. The procedure prevents the more "noble" or least "active" metal or alloy from cathodically depositing on the active metal or alloy. In reality, if an appropriate water treatment program is in place, the actual coupon order will make little or no difference to the results. There is an argument for limiting the number of factors to be considered when analyzing results and if the coupons are installed according to the galvanic series, any high loss rates will not be blamed on, or associated to, galvanic differences (regardless of whether these could, or could not, impact results). As noted previously, working with a standard design and a minimum of variables makes it far easier to assess the potential issues needing redress. Having a removable carbon steel spool piece as part of the coupon rack is a very useful means of visually monitoring pipe wall.conditions over longer-term periods. If these segments are to be utilized, the coupon rack should installed in a location that allows these pieces to be easily inspected (or removed for inspection) without interference. (See example in Figure 2.) 4. Coupons should be placed in the coupon rack such that water flows from the coupon holder to the tip of the coupon. This orientation and direction of flow is promoted as the best means of reducing the potential of erosion at the tip of the coupon. However, at normal flow rates and with no abrasive suspended solids present in the water, erosion is unlikely to be an issue. Several arguments have been put forward on the ideal direction of flow to limit suspended debris from collecting on one or the other end of the coupon (thereby causing under deposit corrosion). Some suggest that the flow should be from the holder to the coupon tip, others from the coupon end to the holder. Both concerns can be addressed, at least in part, by utilizing an upstream strainer as part of the rack design (this will help prevent debris from collecting on either the mounting screw or the coupon tip). Note: where a strainer is incorporated to reduce the impact of any foreign debris, particular attention should be paid to the flow rate during the course of the survey (the trapped material within the strainer may restrict flow and the change in flow rate may impact results). Where practical, the installation of a transparent plastic strainer will indicate whether this might become an issue. (See Parts List Figure 1.) The coupon should be oriented with the broad face in a vertical position. This reduces the accumulation of debris onto the face of the coupon, which can accelerate corrosion. When removed, the coupon should be inspected to ensure it is still properly oriented and secured on the holder. If not, this information should be included in the analysis report. The coupon holder should be equipped with a mark identifying the flat edge of the coupon so that the orientation can be confirmed during installation. Coupons should also be electrically isolated from the holder using suitable plastic washers, screws and nuts where the galvanic difference between the coupon and the mounting hardware is felt to be a concern. 5 Coupon mounting stems 0.5 inches in diameter are recommended. Non-metallic holders are the preferred material of construction but stainless steel is acceptable in alkaline environments. The holder must position the coupon beyond the Tee fitting that the holder is threaded into. It is generally recommended that the coupon holder stem lengths are no less than three (3) inches in length. 5. Water flow through a coupon test rack should be set to emulate system equipment flow rates. In many systems a constant flow between 3 -5 feet per second is normal. Higher velocities (i.e. 8 Ft. I Sec. and above) can cause erosion on soft alloys such as copper-based materials. Calculation of the water velocity in a pipe requires three measurements, OD (Outside Diameter), WT (Wall Thickness) and GPM (Gallons per minute flow). These variables are incorporated into the following formula: Velocity= (0.408 X gpm) I id2 where id is inches specific to the pipe Schedule and MOC Lower water velocities can cause particulate matter to settle onto the coupon resulting in under deposit attack; especially if a biofilm is present. A flow meter or other flow control device should be incorporated to maintain a consistent and repeatable flow rate. This practice facilitates accurate comparisons of coupon rates from one time frame to another. Note: Flow restricting valves usually require a 15 psi drop to operate properly, while flow indicators require roughly a 2 psi differential.

Wherever possible, determine the frequency with which this occurs and include it in the 6 evaluation of results (stagnant flow conditions interfere with film formation and maintenance and may result in higher calculated corrosion rates). Incorporation of a check valve to prevent system drainage helps maintain more consistent results. 6. Normally, the corrosion coupon rack is connected to the return riser to the cooling tower, because the water is warmer than the col dwell supply and potentially more aggressive. It should be noted that coupon results do not reflect corrosion rates of heat exchanger watersides, as there is no heat transfer across coupon surfaces. 7. Water chemistry and quality has a strong impact on corrosion. Temperature, pH, conductivity, bacteria and biofilm, dissolved and suspended solids will influence the rate of attack on the coupons. Uncontrolled microbial populations and/or suspended solids contamination can result in surface accumulations that may harbour sulfate reducing bacteria. This, in turn, can cause localized metal loss resulting in false high corrosion values. Note: The quality of the water treatment program will impact how well the system metallurgies can be protected from most corrosion mechanisms. Surface passivation and control over microbiological populations (and control over suspended material that might harbour SRB's) will impact results. 8. Process contaminations can accelerate attack Organics, gases, acids, alkalis and metals can impact corrosion rates. Sour hydrocarbon leaks will increase corrosion due to sulfide attack on copper or carbon steel. Ammonia leaks can decrease attack on carbon steel due to higher pH. However, ammonia will accelerate attack on copper. Acid contamination will accelerate corrosion on steel and copper. Alkali contamination will accelerate attack on copper, brass and zinc galvanized components. 9. The water chemistry and quality of chemical treatment will influence corrosion rates of coupons. Using pre-passivated coupons prior to installation in the rack is not recommended as this process may result in a false, low corrosion rate. Typically, un- passivated coupons are used in a rack with continuous water flow for a 90 day test period with a proper maintenance level of the system's chemical treatment. Using un-passivated coupons for a short test period of only 30 days will yield a higher initial corrosion rate compared to using passivated coupons. For a 90 day test period, un-passivated coupons are successfully used if the chemical treatment is at a level to passivate the system. Following the above guidelines, acceptable corrosion rates for carbon steel and copper alloys in open recirculating cooling water systems are listed in Table 2. The corrosion rate data and descriptions presented in the Table 2b are not necessarily applicable to all cooling tower systems. It is important to note that some water supplies will present additional challenges to the water treatment professional. Corrosion coupon surveys conducted in these "stressed" waters (i.e. those with high TDS, sulfates and/or chlorides, for example) may need to be evaluated relative to Table 2a or against a hybrid of the Tables 2a and 2b values. Where a make-up water supply is not stressed, the Table 2b values should be considered for HV AC systems. Corrosion rates for closed cooling water systems are listed in Table 3. 7 Table 2a: Quantitative Classification of Corrosion Rates for Open Recirculating Cooling Water Systems-Industrial Cooling Systems and HVAC Systems Operating With High Stress/ High TDS Makeup Waters Corrosion Rates (mpy) Description Carbon Steel CopQ_er Alloys Excellent Less than or equal to 1 Less than or equal to 0.1 Very Good 1 to 3 0.1 to 0.25 Good 3to 5 0.25 to 0.35 Moderate to Fair 5to 8 0.35 to 0.5 Poor 8to 10 0.5 to 1 Very Poor to Severe > 10 >1 Table 2b: Quantitative Classification o:( Corrosion Rates for Open Recirculating Cooling Water Systems -HV AC for Institutional and Commercial Fac:ilities.

To prevent any alteration to the coupon surface before installation, do not touch coupon surface with fingers or contaminate surfaces • Upon removal, coupons should be gently blotted dry using only a clean paper towel. " Coupons should be stored in suitable corrosion resistant envelopes to prevent corrosion both prior to and following the survey period.
