MAXIMUM CONTAMINANT LEVEL VIOLATION MCL, LRAA/TTHM

The Texas Commission on Environmental Quality (TCEQ) has notified the Hudson WSC TX0030023 that the drinking water being supplied to customers had exceeded the Maximum Contaminant Level (MCL) for total trihalomethanes. The U.S. Environmental Protection Agency (U.S. EPA) has established the MCL for total trihalomethanes to be 0.080 milligrams per liter (mg/L) based on the locational running annual average (LRAA), and has determined that it is a health concern at levels above the MCL. Analysis of drinking water in your community for total trihalomethanes indicates a compliance value in quarter three 2025 of 0.081 mg/L for DBP2-04 and 0.083 mg/L for DBP2-03.

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

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

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

We are taking the following actions to address this issue: We are lowering levels in water tanks to reduce the Cl2 contact time.
