Special Notice - Required language for ALL community public water systems:
You may be more vulnerable than the general population to certain microbial contaminates, such as Cryptosporidium, in drinking water. Infants, some elderly, or immunocompromised persons such as those undergoing chemotherapy for cancer; those who have undergone organ transplants; those who are undergoing treatment with steroids; and people with HIV/AIDS or other immune system disorders can be particularly at risk from infections. You should seek advice about drinking water from your physician or health care provider. Additional guidelines on appropriate means to lessen the risk of infection by Cryptosporidium are available from the Safe Drinking Water Hotline (1-800-426-4791).

OUR DRINKING WATER MEETS OR EXCEED 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 test and is presented on the opposite side of this page. 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 contaminates, and organic chemical contaminants.

Where do we get our drinking water?
Our drinking water is obtained from GROUND water sources. It comes from the following Lake/River/Reservoir/Aquifer: TRINITY UPPER, TRINITY LOWER, GUADALUPE RIVER. A Source Water Susceptibility Assessment for your drinking water sources(s) is currently being updated by the Texas Commission on Environmental Quality. This information describes 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 allows us to focus our source water protection strategies. Some of this source assessment information will be available later this year on Texas Drinking Water Watch at http;//www.tceq.state.tx.us/DWW/. For more information on source water assessments and protection efforts at our system, please contact us.

ALL drinking water may contain contaminants.
When 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 EPA’s Safe Drinking Water Hotline at (1-800-426-4791).

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.

About the Following Pages
The pages that follow list 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. 
MCL’s are set as close to the MCLG’s 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.  MCLG’s 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.
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.
