The Texas Commission on Environmental Quality (TCEQ) has notified the LOMETA REGIONAL WATER SYSTEM, TX1410002, 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 trihalomethanes 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 quarter four 2018 of 0.082 mg/L for DBP2-02, which is the area surrounding and including 1468 FM 1047.
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 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 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 have added additional treatment to the clearwell and storage tanks to reduce the concentration and formation of total trihalomethanes. We have also increased our flushing in the distribution system. With these actions we met the total trihalomethane limits during the third quarter. Unfortunately, the heavy rains in October increased the amount of naturally occurring organics in our raw water reservoir and we were not able to maintain the required level. Corix Utilities (Texas) has hired an engineering firm to look at alternative treatment options for the Lometa Regional Water Treatment Plant. In the coming year we will be evaluating their recommendations.
Please share this information with all people who drink this water, especially those who may not have received this notice directly (i.e., people in apartments, nursing homes, schools, and businesses). You can do this by posting this notice in a public place or distributing copies by hand or mail.
If you have any questions regarding this matter, you may contact Gloria Broussard at 512-306-4001
