This drinking water quality report shows results of tests conducted by the water utility and provided to the Environmental Working Group (EWG) by the Texas Commission on Environmental Quality . It is part of EWG's national database that includes 47,667 drinking water utilities and 20 million test results. Water utilities nationwide detected more than 300 pollutants between 2004 and 2009. More than half of these chemicals are unregulated, legal in any amount. Despite this widespread contamination, the federal government invests few resources to protecting rivers, reservoirs, and groundwater from pollution in the first place. The information below summarizes test results for this utility and lists potential health concerns.

	This Drinking Water System	National Average
Exceed Health GuidelinesTests showing chemicals at concentrations above health guidelines established by federal and state health agencies. These guidelines are typically set at a levels that pose no significant health risk.	2 chemicals	4
Health Standard ExceedencesChemicals detected at concentrations above the legal limit, the Maximum Contaminant Level (MCLs) established by the U.S. EPA. Most MCLs are based on annual averages, so exceeding the MCL for one test does not necessarily indicate that the system is out of compliance.	0 chemicals	0.5
Pollutants FoundThe total number of contaminants detected since 2004, according to data provided by the state water agency.	12 chemicals	8
Tests ConductedThe total number of number of water quality tests conducted by water utilities and recorded in data provided by the state water agency.	112 tests	420

Contaminants Exceeding Health Guidelines

Contaminant	Average/ Maximum Result	Health Limit Exceeded	Legal Limit Exceeded	Testing History -Tested      -Detected      -Over Health Guidelines      -Over Legal Limit*
BromoformBromoform is a disinfection byproduct from the trihalomethane (THM) family, and is formed when chlorine, chloramines or other disinfectants react with organic and inorganic matter in water.	2.8 ppb 5.6 ppb	Yes MCLGA non-enforceable health goal that is set at a level at which no known or anticipated adverse effect on the health of persons occurs and which allows an adequate margin of safety. Source: U.S. Environmental Protection Agency.: 0 ppb	No 80 ppb
DibromochloromethaneDibromochloromethane is a disinfection byproduct from the trihalomethane (THM) family, and is formed when chlorine, chloramines or other disinfectants react with organic and inorganic matter in water.	1.6 ppb 3.2 ppb	Yes 0.4 ppb	No 80 ppb
NOTE: Each dot in the above graph represents one month. * Water utilities are noted as exceeding the legal limit if any test is above the maximum contaminant level (MCL). Most MCLs are based on annual averages so exceeding the MCL for one test does not necessarily indicate that the system is out of compliance.

State Limits may be lower.
ChloromethaneChloromethane is a naturally occuring chemical that forms during combustion of plant material; it may be released from the manufacture of silicone, rubber and pesticides, and also forms as a byproduct of water disinfection.	0.68 ppb 0.68 ppb	No 30 ppb	Legal at any levelThis is the Federal Limit. State Limits may be lower.
ManganeseManganese is a naturally occurring element released from mineral deposits as well as industrial use.	8.49 ppb 8.49 ppb	No 50 ppb	No 50 ppb
CopperCopper is a naturally occuring metal and drinking water contaminant that enters tap water by corrosion of household plumbing systems and erosion of natural deposits.	8.1 ppb 8.1 ppb	No 300 ppb	No 1000 ppb
Chromium (total)Chromium is a metal that pollutes drinking water due to discharge from steel and pulp mills and erosion of natural deposits.	9.79 ppb 9.79 ppb	No 100 ppb	No 100 ppb
TolueneToluene is a pollutant from petroleum refineries and a chemical used in plastics manufacturing as well as the pharmaceutical, paint and furniture industries.	1.59 ppb 1.59 ppb	No 150 ppb	No 1000 ppb

EPA Violation Summary

Violation Date of Violation Failure to report information to the public or state agency in the Consumer Confidence Report 2004/07/01 - 2005/03/31

Information on violations is drawn directly from EPA's national violations database in the Agency's Safe Drinking Water Information System. Analyses by others have raised questions about the quality of the information in EPA's database. For the purposes of this investigation, EWG is not showing below or including in our analyses, those violations for individual water suppliers that occurred on days for which the total number of violations assigned by EPA to that water supplier was greater than 20. This criteria was based on common characteristics of incorrect violations data as identified by water utilities, from a review of EPA's violations data by several hundred utilities prior to the release of EWG's investigation.
