How is my Drinking Water Quality?
How to find information about your drinking water whether it comes from a public water system or a private well.
Does your drinking water come from a public water system?
Public water systems in Texas are required to regularly test their water for 102 different contaminants to ensure it meets all federal and state drinking water standards.
Consumer Confidence Report
You can learn about the quality of your drinking water by reading your water system’s annual drinking water quality report, also called a Consumer Confidence Report (CCR).
Most public water systems are required to provide this report to you, their customer, by July 1 each year. If you do not pay your own water bill — for example, if you live in an apartment or condo or rent house — you may need to contact a property manager for more information or check online to see if their CCR has been posted.
The CCR includes information about the source(s) of water used (rivers, lakes, reservoirs, or aquifers), chemical and bacteriological contaminants, compliance with drinking water rules, educational health information, water system contact information, and public participation opportunities.
Drinking Water Watch
TCEQ’s Texas Drinking Water Watch (DWW) contains information on sources, contaminants, and violations for all public water systems in Texas. Refer to the Instructions for Texas Drinking Water Watch should you need assistance with the database.
Does your drinking water come from a private well?
If you are a private well owner, you are responsible for regularly testing your well water to ensure it is safe for drinking and cooking.
- Information about potential contaminants and recommended home water testing is available through the Centers for Disease Control and Prevention and the U.S. Environmental Protection Agency
- When testing private well water, the TCEQ recommends using an accredited drinking water laboratory
