		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.

	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.  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 (800-426-4791).

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

		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:  EVANGELINE, UNKNOWN AQUIFER.  TCEQ completed an assessment of our source water and results indicate that some of our sources are susceptible to certain contaminants.  The sampling requirements for our water system are based on this susceptibility and previous sample data.  Any detection of these contaminants will be found in this report.  If we receive or purchase water from another system, their susceptibility is not included in this assessment.  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 EPS’s Safe Drinking Water Hotline (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 concern.  Therefore, secondaries are not required to be reported in this document but they may greatly affect the appearance and taste of your water.
	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 knows 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.
