Public Notice of Total Trihalomethane (TTHM) MCL Violation
March 19, 2020
The Texas Commission on Environmental Quality (TCEQ) has notified the HWSC TX 0030023 that the drinking water being supplied to customers had exceeded the Maximum Contaminant Level (MCL) for total trihalomethanes. The US Environment Protection Agency (US EPA) has established the MCL for total trihalomehtanes to be 0.080 milligrams per liter (mg/L) based on 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;
* 1Q2020 of .084 mg/L for 871 POST OAK RD., LUFKIN (DBP2-03)
* 4Q2019 of .094 mg/L for 871 POST OAK RD., LUFKIN (DBP2-03)
Trihalomethanes are a group of volatile organic compounds that are formed when chlorine, added to the water during the treatment process for disinfection, reacts with naturally-occurring organic matter in the water.
Some people who drink the water containing trihalomehtanes in excess of the MCL over many years may experience problems with their 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.
