Special Notice for elderly, infants, cancer patients, All drinking water may contain contaminants. people with HIV/AIDS or other immune problems: When drinking water meets federal standards there may not be any Some people may be more vulnerable to contaminants in drinking water health based benefits to purchasing bottled water or point of use than the general population. Immuno-compromised persons such as devices. Drinking water, including bottled water, may reasonably be persons with cancer undergoing chemotherapy, persons who have expected to contain at least small amounts of some contaminants.The undergone organ transplants, people with HIV/AIDS or other immune presence of contaminants does not necessarily indicate that the water system disorders, some elderly, and infants can be particularly at risk poses a health risk. More information about contaminants and potential from infections.These people should seek advice about drinking water health effects can be obtained by calling the EPA Safe Water Hotline from their health care providers.The EPA/Centers for Disease Control (800)426-4791. and Prevention (CDC)guidelines on appropriate means to lessen the Secondary Constituents: risk of infection by Cryptosporidium and other microbial contaminants are available from the Safe Drinking Water Hotline(1-800-426-4791). Many constituents(such as calcium, sodium,or iron)which are often found in drinking water can cause taste, color, and odor problems.The Public Participation Opportunities: taste and odor constituents are called secondary constituents and are We encourage public interest and participation in our community's regulated by the State of Texas, not the EPA.These constituents are decisions affecting drinking water. Regular City Council meetings take not causes for health concern.Therefore, secondaries are not required place on the second&fourth Tuesdays of the month, at 7 p.m. in Euless to be reported in this document but they may greatly affect the City Hall, 201 N.

Our Drinking Water Meets or Exceeds All Federal (EPA) Definitions: Drinking Water Requirements Maximum Contaminant Level Goal or MCLG:The level of a This report is a summary of the quality of the water we provide our contaminant in drinking water below which there is no known or expected customers.The analysis was made by using the data from the most health risk. MCLGs allow for a margin of safety. recent U.S. Environmental Protection Agency(EPA) required tests and Maximum Contaminant Level or MCL:The highest permissible is presented on the opposite site.We hope this helps you become more level of a contaminant in drinking water. MCLs are set as close to the knowledgeable about what's in your drinking water. MCLGs as feasible using the best available treatment technology. Maximum Residual Disinfectant Level (MRDL): The highest Water Sources: level of disinfectant allowed in drinking water.There is convincing evidence Drinking water sources(both tap water and bottled water) include rivers, that addition of a disinfectant is necessary for control of microbial lakes, streams, ponds, reservoirs,springs and wells.As water travels contaminants. over the surface of the land or through the ground, it dissolves Maximum Residual Disinfectant Level Goal (MRDLG):The naturally-occurring minerals and in some cases, radioactive material, level of a drinking water disinfectant below which there is no known or and can pick up substances resulting from the presence of animals or expected risk to health. MRDLGs do not reflect the benefits of the use of from human activity. Contaminants that may be present in source water disinfectants to control microbial contamination. before treatment include: microbes, inorganic contaminants, pesticides, Treatment Technique (TT):A required process intended to reduce herbicides, radioactive contaminants&organic chemical contaminants. the level of a contaminant in drinking water.

MFL Million Fibers per liter,a measure of asbestos This page lists all of the federally regulated or monitored contaminants which have been found in your drinking water.The U.S.EPA requires water systems to test for up to 97 contaminants.

Unregulated Initial Distribution System Evaluation for Disinfection Byproducts-This evaluation is sampling required by EPA to determine the range of total trihalomethane and haloacetic acid in the system for future regulations.The samples are not used for compliance,and may have been collected under non-standard conditions.EPA requires the data to be reported here.

Lead and Copper-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.This water supply 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 30 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 httg://www.epa.gov/safewater/lead.

Turbidity-Turbidity has no health effects.However,turbidity can interfere with disinfection and provide a medium for microbial growth.Turbidity may indicate the presence of disease-causing organisms.These organisms include bacteria,viruses and parasites that can causes mgtoms such as nausea,cramps,diarrhea and associated headaches.

Total Coliform-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 hardier than many disease-causing organisms;therefore,their absence from water is a good indication that the water is microbiologicall safe for human consumption.
