Mandatory Language for a Maximum Contaminant Level Violation MCL, LRAA/ TTHM
The Texas Commission on Environmental Quality (TCEQ) has notified the JACKSON WSC TX2120016 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 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 the 3rd quarter of 2019 of 0.082 mg/L for DBP2-02.
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 liver, kidney, or central nervous system, 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: Increased flushing, lowered residual in Plant 1 and have a recheck scheduled for 11/7/2019.
Please share this information with all the people who drink the 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 questions regarding this matter, you may contact Amber Durham System Manager at 903-566-1320.
