These well fields withdraw groundwater from several underground aquifers and provide high quality, clean water that requires less treatment than surface water. However, the cost of transporting and maintaining the wells is also higher than using surface water. Considering this fact and Montgomery s growing population, in 965 the C.T. Perry Water Purification Plant was built on the Tallapoosa River. Today, this plant has a capacity of 6 million gallons of water per day (MGD) and accounts for 6% of Montgomery s water supply. The Day Street Pump Station (2 MGD), the Hanan Water Treatment Plant (2.5 MGD), and all well fields account for the remaining 4%. Together, our water sources provide water for Montgomery and surrounding areas. A source water assessment was conducted for the water supply of Montgomery Water Works including both the surface water and groundwater. An investigation of potential sources of contamination located within our water supply area was conducted. Each source was examined individually to determine the possible impact on the raw water supply. The majority of sources identified during the investigation pose little or no significant threat to our water supply. For more information about the source water assessment or to view a copy of the reports resulting from this investigation, please contact us at (334) 266. ADDITIONAL INFORMATION All drinking water, including bottled water, may reasonably be expected to contain at least small amounts of some contaminants. The presence of contaminants does not necessarily indicate that water poses a health risk. More information about contaminants and potential health effects can be obtained by calling the Environmental Protection Agency s Safe Drinking Water Hotline ( ). The sources of drinking water (both tap water and bottled water) include rivers, lakes, streams, ponds, reservoirs, springs, and wells. As water travels over the surface of the land or through the ground, it dissolves naturally occurring minerals and radioactive material, and it can pick up substances resulting from the presence of animals or from human activity. To ensure that tap water is safe to drink, EPA prescribes regulations that limit the amount of certain contaminants in water provided by public water systems. FDA regulations establish limits for contaminants in bottled water. If present, elevated levels of lead can cause serious health problems, especially for pregnant women and young children. Lead in drinking water is primarily from materials and components associated with service lines and home plumbing. Montgomery Water Works and Sanitary Sewer Board is responsible for providing high quality drinking water, but cannot control the variety of materials used in plumbing components. When your water has been sitting for several hours, you can minimize the potential for lead exposure by flushing your tap for 3 seconds to 2 minutes before using your water for drinking or cooking. If you are concerned about lead in your water, you may wish to have your water tested.

4 D uring 26, many of Montgomery Water Works water and wastewater plants were recognized for excellence of operation. These awards demonstrate our continued commitment and dedication to provide the best possible water and wastewater service to you, our customers. Awards were received from the U.S. Environmental Protection Agency (EPA), Alabama Department of Environmental Management (ADEM), and Alabama Water Pollution and Control Association (AWPCA). EPA and ADEM AWARD Area Wide Optimization Program Thirteen Year Optimized Plant Award C. T. Perry Water Purification Plant AWPCA AWARDS Ground Water Plants, 5, 25, Population Best Operated Plant Horse Farm Water Treatment Plant Award of Excellence Wallahatchee Water Treatment Plant Award of Excellence Kilby Well Water Treatment Plant Ground Water Plants Greater than, Population Award of Excellence Hanan Water Treatment Plant Wastewater Mechanical Plant Bio Filter/Trickling Filter Winner Econchate Wastewater Treatment Plant Award of Excellence Towassa Wastewater Treatment Plant Wastewater Mechanical Plant Greater than. MGD Award of Excellence Catoma Wastewater Treatment Plant The Court Street Pumping Station was recognized by the American Water Works Association (AWWA) with its Landmark Award at the April 8th Montgomery Water Works Board meeting. The Award recognizes a North American Water Landmark at least 5 years old that has had a direct and significant relationship with water supply, treatment, distribution, or technological development. The Court Street Pumping Station joins the ranks of other AWWA Landmarks such as the Hoover Dam and the Chicago Water Tower. This is one of only five Landmark Awards presented nationwide this year. Furthermore, it is one of only four such landmarks ever designated in Alabama. Court Street Pumping Station was built in 886 to provide water to the city from artesian wells located on the site of the station. It was originally steam powered, receiving weekly shipments of coal via rail. Over the years it was upgraded as technology for safe drinking water advanced. The pumping station provided water continuously from 886 until 22 when it was retired from service. Health Information Some people may be more vulnerable to contaminants in drinking water than the general population. People who are immunocompromised, such as cancer patients undergoing chemotherapy, organ transplant recipients, HIV / AIDS positive or other immune system disorders, some elderly, and infants can be particularly at risk from infections. People at risk should seek advice about drinking water from their health care providers. EPA / CDC guidelines on appropriate means to lessen the risk of infection by Cryptosporidium and other microbiological contaminants are available from the Safe Drinking Water Hotline ( ). Cryptosporidium and Giardia Cryptosporidium and Giardia are microscopic organisms that are relatively widespread in the environment. Surface waters, such as lakes and rivers that contain a high amount of sewage contamination or animal wastes are more susceptible to increased numbers of these parasites. The Montgomery Water Works and Sanitary Sewer Board is taking steps to make sure that these organisms do not pose a problem in your drinking water. Current protection measures taken at the C.T. Perry Water Purification Plant include chlorination, filtration, and monitoring turbidity levels and particle sizes. Additionally, routine backwashing of the filters helps to eliminate the chances of finding these organisms in treated water. Occasionally, we have found these organisms in the raw water, but neither Cryptosporidium nor Giardia has ever been detected in the finished water. We will continue to monitor for these and other contaminants and take all necessary precautions to ensure that your water is safe for your use. DEFINITIO Primary Standards Used as guides to protect public health. Primary standards include maximum contaminant levels, maximum contaminant level goals, action levels, and treatment techniques. Secondary Standards Guidelines to assure good aesthetic quality of water. Secondary standards apply to contaminants that affect the taste, odor or color of water, stain sinks or bathtubs, or interfere with treatment processes. Maximum Contaminant Goal (G) The level of a contaminant in drinking water below which there is no known or expected risk to health. Gs allow for a margin of safety. Maximum Contaminant () The highest level of a contaminant that is allowed in drinking water. s are set as close to the Gs as feasible using the best available treatment technology. Maximum Residual Disinfectant Goal (MRDLG) The level of a drinking water disinfectant below which there is no known or expected risk to health. MRDLGs do not reflect the benefits of the use of disinfectants to control microbial contaminants. Maximum Residual Disinfectant (MRDL) The highest level of a disinfectant allowed in drinking water. There is convincing evidence that addition of a disinfectant is necessary for control of microbial contaminants. Treatment Technique A required process intended to reduce the level of a contaminant in drinking water. Action The concentration of a contaminant that triggers treatment or other requirement a water system shall follow. Based on a study conducted by ADEM with the approval of the EPA a statewide waiver for the monitoring of asbestos and dioxin was issued. Thus, monitoring for these contaminants was not required.

8 27 Annual Drinking Water Quality Report Walnut Hill Water Authority JanuaryDecember 26 Is my water safe? Last year, as in years past, your tap water met all U.S. Environmental Protection Agency (USEPA) and the Alabama Department of Environmental Management (ADEM) drinking water health standards. Your local water officials vigilantly safeguard its water supplies and once again we are proud to report that our system has not violated a maximum contaminant level or any other water quality standards. We're pleased to present to you this year's Annual Drinking Water Quality Report. This report is designed to inform you about the quality water and services we deliver to you every day. Our constant goal is to provide you with a safe and dependable supply of drinking water. We want you to understand the efforts we make to continually improve the water treatment process and protect our water resources. We are committed to ensuring the quality of your water. Our source water comes from the Adams Filter Plant, which is located in Alex City. The water we supply to our customers requires no specialized treatment. However, Chlorine is added to the water as disinfectant and the required residual is maintained to protect your drinking water from any possible outside contaminants. The Walnut Hill Water Authority routinely completes a water storage facility inspection plan, and utilizes a Bacteriological Monitoring Plan and a Cross Connection Policy is in place to insure good safe drinking water for our customers. Alexander City has completed a Source Water Assessment Plan, which is available at their office for review. This report provides information about potential sources of contamination and is set up to help protect our source. We want our valued customers to be informed about their water utility. If you want to learn more, please attend any of our regularly scheduled Board meetings. They are held on the 3rd Monday of the month at the Walnut Hill Water Authority office that is located at 779 Hwy 5 and begin at 5:3 p.m. The members of the Board of Directors are: Ben Sands, Chairman, Sandra Carlisle, Ernie Barnes Important Drinking Water Definitions: Action (AL) The concentration of a contaminant that triggers treatment or other requirements that a water system shall follow. Maximum Contaminant () The highest level of a contaminant that is allowed in drinking water. s are set as close to the Gs as feasible using the best available treatment technology. Maximum Contaminant Goal (G) The level of a contaminant in drinking water below, which there is no known or expected risk to health. Gs allow for a margin of safety. Maximum Residual Disinfectant (MRDL) The highest level of a disinfectant allowed in drinking water. There is convincing evidence that addition of a disinfectant is necessary for control of microbial contaminants. Maximum Residual Disinfectant Goal (MRDLG) The level of a drinking water disinfectant below which there is no known or expected risk to health. MRDLGs do not reflect the benefits of the use of disinfectants to control microbial contaminants. Millirems per year (mrem/yr) Measure of radiation absorbed by the body. Nephelometric Unit (NTU) Nephelometric turbidity unit is a measure of the clarity of water. in excess of 5 NTU is just noticeable to the average person. NonDetects () Laboratory analysis indicates that the constituent is not present. Parts per million () or Milligrams per liter (mg/l) One part per million corresponds to one minute in two years or a single penny in $,. Parts per billion () or Micrograms per liter (µg/l) One part per billion corresponds to one minute in 2, years, or a single penny in $,,. Parts per trillion (ppt) or Nanograms per liter (ng/l) One part per trillion corresponds to one minute in 2,, years, or a single penny in $,,,. Parts per quadrillion (ppq) or Picograms per liter (pg/l) One part per quadrillion corresponds to one minute in 2,,, years or one penny in $,,,,. Picocuries per liter (pci/l) Picocuries per liter is a measure of the radioactivity in water. Treatment Technique (TT) A required process intended to reduce the level of a contaminant in drinking water. Threshold Odor Number (T.O.N.) The greatest dilution of a sample with odorfree water that still yields a justdetectable odor. Variances & Exemptions ADEM or EPA permission not to meet an or a treatment technique under certain conditions. Explanation of reasons for variance/exemptions Based on a study conducted by ADEM with the approval of the EPA a statewide waiver for the monitoring of asbestos and dioxin was issued. Thus monitoring for these contaminants was not required. The Walnut Hill Water Authority routinely monitors for contaminants in your drinking water according to Federal and State laws. Unless otherwise noted, the data presented in the following tables show the results of our monitoring period of January st to December 3 st, 26.

The purpose of unregulated contaminant monitoring is to assist EPA in determining the occurrence of unregulated contaminants in drinking water and whether future regulation is warranted. All drinking water, including bottled drinking water, may be reasonably expected to contain at least small amounts of some contaminants. It's important to remember that the presence of these contaminants does not necessarily pose a health risk. The EPA or ADEM requires us to monitor for certain contaminants less than once per year because the concentrations of these contaminants do not change frequently.

Lead in drinking water is primarily from materials and components associated with service lines and home plumbing. Walnut Hill Water Authority is responsible for providing high quality drinking water, but cannot control the variety of materials used in plumbing components. When your water has been sitting for several hours, you can minimize the potential for lead exposure by flushing your tap for 3 seconds to 2 minutes before using water for drinking or cooking. If you are concerned about lead in your water, you may wish to have your water tested. Information on lead in drinking water, testing methods, and steps you can take to minimize exposure is available from the Safe Drinking Water Hotline or at The sources of drinking water (both tap water and bottled water) include rivers, lakes, streams, ponds, reservoirs, springs, and wells. As water travels over the surface of the land or through the ground, it dissolves naturally occurring minerals and radioactive material, and it can pick up substances resulting from the presence of animals or from human activities. As you can see by the tables, our system had no monitoring violations of allowable limits of contaminants in drinking water. We re proud that your drinking water meets or exceeds all Federal and State requirements. We have learned through our monitoring and testing that some contaminants have been detected. The EPA has determined that your water IS SAFE at these levels. s are set at very stringent levels. To understand the possible health effects described for many regulated contaminants, a person would have to drink 2 liters of water every day at the level for a lifetime to have a oneinamillion chance of having the described health effect. Total Coliform: The Total Coliform Rule requires water systems to meet a stricter limit for coliform bacteria. Coliform bacteria are usually harmless, but their presence in water can be an indication of diseasecausing bacteria. When coliform bacteria are found, special followup tests are done to determine if harmful bacteria are present in the water supply. If this limit is exceeded, the water supplier must notify the public by newspaper, television or radio. To comply with the stricter regulation, we have increased the average amount of chlorine in the distribution system. Some people may be more vulnerable to contaminants in drinking water than the general population. People who are immunocompromised such as cancer patients undergoing chemotherapy, organ transplant recipients, HIV/AIDS positive or other immune system disorders, some elderly, and infants can be particularly at risk from infections. People at risk should seek advice about drinking water from their health care providers. EPA (Environmental Protection Agency)/CDC (Center of Disease Control) guidelines on appropriate means to lessen the risk of infection by Cryptosporidium and other microbiological contaminants are available from the Safe Drinking Water Hotline. All Drinking water, including bottled drinking water, may reasonably be expected to contain at least small amounts of some contaminants. More information about contaminants and potential health effects can be obtained by calling the Environmental Protection Agency s Safe Drinking Water Hotline ( ). Thank you for allowing us to continue providing your family with clean, quality water this year. In order to maintain a safe and dependable water supply we sometimes need to make improvements that will benefit all of our customers. These improvements are sometimes reflected as rate structure adjustments. Thank you for understanding. We at the Walnut Hill Water Authority work around the clock to provide top quality water to every tap. We ask that all our customers help us protect our water sources, which are the heart of our community, our way of life and our children s future.
