Violation for TTHM's 09/24/2026-3rd Quarter

The Texas Commission on Environmental Quality (TCEQ) has notified the Redland WSC TX0030028 that the drinking water being supplied to customers in the Duncan Slough area had exceeded the Maximum Containment Level (MCL) for total trihalomethanes. The US Environmenta Protection Agency (U.S. EPA) has established the MCL for total trihalomethanes to be 0.080 milligram per liter (mg/l). Based on locational running annual average (LRAA), and has determined that it is a health concern at levels above MCL. Analysis of drinking water in your community for total trihalomethanes indicates a compliance value in quarter 3 of 2026 of 0.084 mg/l, for DBP2-01. 

Trihalomethanes are a group of volatile organic compounds that are formed when chlorine added to water during the treatment process for disinfection reacts with naturally-occurring organic matter in the water.  

Some people who drink water containing trihalomethanes in excess of the MCL over many years may experience problems with their liver, kidney or central nervous systems and may have an increase of getting cancer.

You do not need to use an alternative water supply. However, if you have health concerns you may want to talk with your doctor to get more information about how this may affect you. 

We are taking the following actions to address this issue:

1. Flushing the water line in the affected area for a longer period of time. We will flush thousands of gallons more water to help with this matter.

2. Flushing the affected area more frequently.

3. I have reached out to TRWA for assistance with this matter.

Please share this information with all people who drink this water, especially those who may not have received this notice directly.

If you have any questions regarding this matter, you may contact Redland Water Supply Corporation at 936-634-5070.
