We test our water using sophisticated equipment and advanced procedures. Acton Municipal Utility District’s water meets state and federal standards for both appearance and safety. This annual “Consumer Confidence Report,” required by the Safe Drinking Water Act (SDWA), tells you where your water comes from, what our tests show about it, other things you should know about drinking water and AMUD. We Are Proud To Report That The Water Provided ByActon Municipal Utility District Meets Or Exceeds All Federal (EPA) Drinking Water Requirements This report is a summary of the quality of the water we provide our customers. The analysis was made by using the data from the most recent U.S. Environmental Protection Agency (EPA) required tests and is presented in the attached pages. We hope this information helps you become more knowledgeable about what’s in your drinking water. WATER SOURCES: 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 in some cases, radioactive material, and can pick up substances resulting from the presence of animals or from human activity. Contaminants that may be present in source water before treatment include: microbes, inorganic contaminants, pesticides, herbicides, radioactive contaminants, and organic chemical contaminants.En EspañolEste informe incluye información importante sobre el agua potable.

AMUD has grown from 6,252 water connections in December 2006 to 6,440 water connections in December of 2007. A number of improvements to our water system have been completed. AMUD has replaced approximately 4,000 feet of 2 inch water mains with new 8 inch water mains and installed new service lines and fire hydrants. AMUD completed construction of 2 new water supply wells located at Pecan Plantation and Main Place. In addition AMUD is in the process of rehabilitating an old well located at the front gate of Pecan Plantation. These improvements will continue to provide our customers with an ample supply of water. Public Participation OpportunitiesWe encourage public interest and participation in our community’s decisions affecting drinking water. Regular Board Meetings occur on the third Monday of every month, at the District Office, 2001 Fall Creek Hwy, the meetings begin at 9:00 AM. The public is welcome. Consult our Web Site at www.amud.com and/or contact us at (817) 326-4720, for further information, see U.S. Environmental Protection Agency (EPA) water information at www.epa.gov/safewater/. Where do we get our drinking water?Acton Municipal Utility District is supplied by surface water from Lake Granbury. We also pump groundwater from the Trinity and Paluxy Aquifers through twenty-one water wells located throughout our District. These sources are blended throughout the system. The water from Lake Granbury is treated at the SWATS Plant located on Matlock Road off of Highway 167. A Source Water Susceptibility Assessment for your drinking water sources(s) is currently being updated by the Texas Commission on Environmental Quality (TCEQ) and will be provided to us this year. This report will describe the susceptibility and types of constituents that may come into contact with your drinking water source based on human activities and natural conditions. The information contained in the assessment will allow us to focus our source water protection strategies. For more information on source water assessments and protection efforts at our system, please contact us. Special Notice for the ELDERLY, INFANTS, CANCER PATIENTS, people with HIV/AIDS or other immune problems: Some people may be more vulnerable to contaminants in drinking water than the general population. Immuno-compromised persons such as persons with cancer undergoing chemotherapy, persons who have undergone organ transplants, people with HIV/AIDS or other immune system disorders, some elderly, and infants can be particularly at risk from infections. These people should seek advice about drinking water from their health care providers. The EPA/Centers for Disease Control and Prevention (CDC) guidelines on appropriate means to lessen the risk of infection by Cryptosporidium and other microbial contaminants are available from the Safe Drinking Water Hotline (1-800-426-4791). All Drinking Water May Contain ContaminantsWhen drinking water meets federal standards there may not be any health-based benefits to purchasing bottled water or point of use devices. 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 Hotline (800-426-4791). Secondary Constituents – Many constituents (such as calcium, sodium, or iron) which are often found in drinking water, can cause taste, color, and odor problems. The taste and odor constituents are called secondary constituents and are regulated by the State of Texas, not the EPA. These constituents are not causes for health concerns. Therefore, secondaries are not required to be reported in this document but they may greatly affect the appearance and taste of your water.The Following PageThe page that follows lists all of the federally regulated or monitored contaminants which have been found in your drinking water. U.S. EPA requires water systems to test up to 97 contaminants. DEFINITIONS Maximum Contaminant Level (MCL) The highest permissible level of a contaminant in drinking water. MCLs are set as close to the MCLGs as feasible using the best available treatment technology. Maximum Contaminant Level Goal (MCLG) The level of a contaminant in drinking water below which there is no known or expected health risk. MCLGs allow for a margin of safety. Maximum Residual Disinfectant Level (MRDL) The highest level of disinfectant allowed in drinking water. There is convincing evidence that addition of a disinfectant is necessary for control of microbial contaminants. Maximum Residual Disinfectant Level Goal (MDRLG) The level of a drinking water disinfectant below which there is no known or expected risk to health. MRDLG’s do not reflect the benefits of the use of disinfectants to control microbial contamination. Treatment Technique (TT) A required process intended to reduce the level of a contaminant in drinking water. Action Level (AL) The concentration of a contaminant which, if exceeded, triggers treatment or other requirements which a water system must follow.

| Coliforms | What are coliforms? Total coliform bacteria are used as indicators of microbial contamination of drinking water because testing for them is easy. While not disease-causing organisms themselves, they are often found in association with other microbes that are capable of causing disease. Coliform bacteria are more hardy than many disease-causing organisms; therefore, their absence from water is a good indication that the water is microbiologically safe for human consumption. Fecal coliform bacteria and, in particular, E. coli, are members of the coliform bacteria group originating in the intestinal tract of warm-blooded animals and are passed into the environment through feces. The presence of fecal coliform bacteria (E. coli) in drinking water may indicate recent contamination of the drinking water with fecal material. The following table indicates whether total coliform or fecal coliform bacteria were found in the monthly drinking water samples submitted for testing by your water supplier last year. |
