Consumer Confidence Report

System # 1290010

 

Every year ASWSC is required to provide its members with the Annual Drinking Water Quaility Report.  This report is a summary of the quality of water we provide our members.  The following pages list all the federally regulated or monitored contaminants which have been found in your drinking water .  The U.S Environmental Protection Agency (EPA) requires water systems to test for up to ninty-seven (97) contaminants.  The analysis was made by using the data from the most recent EPA required tests. We hope this information helps you become more knowledgeable about what is in your drinking water.  We are proud to report that our drinking water meets or exceeds all federal (EPA) drinking water requirements.

 

 

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 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. 

Where do we get our drinking water?

Our drinking water is obtained from SURFACE water sources.  It comes from the following Lake/River/Reservoir/Aquifer: Lake Tawakoni.  A Source Water Susceptibility Assessment for your drinking water source(s) is currently being updated by the Texas Commission on Environmental Quality and will be provided to us this year.  The 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.

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 (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 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.

Total Coliform   REPORTED MONTLY TESTS FOUND NO COLIFORM BACTERIA.

Fecal Coliform   REPORTED MONTHLY TESTS FOUND NO FECAL COLIFORM BACTERIA.
