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&fourthTuesdays 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 risk to health. 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, in some cases, radioactive material, and level of a drinking water disinfectant below which there is no known or can pick up substances resulting from the presence of animals or from expected risk to health. MRDLGs do not reflect the benefits of the use of 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.

It is supplied by Trinity River Authority(Cedar Creek and Richland Chambers Lakes)and Euless water wells(Trinity Aquifer).A Source Water Susceptibility Assessment for your drinking water source(s) is Abbreviations currently being updated by TCEQ and will be provided to us this year.

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 or•anisms include bacteria,viruses and•arasites that can causes m•toms such as nausea,crams,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 microbiolo•icall safe for human consumption.
