Mandatory language for a Maximum Contaminant level Violation MCl, lRAA/TTHM

The Texas Commission on Environmental Quality (TECQ) has notified the CITY OF ZAVALLA TX0030030 that the drinking water being supplied to customers has exceeded the Maximum contaminant Level 9MCLf for total trihalomethanes. The U.S. Environmental Protection Agency (U.S. EPA) has established the MCL FOR TOTAL TRIHALMOETHANES 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 community for total trihalomethanes indicates a compliance value in quarter two 2022 of 0.093 mg/L for DBP2-01.


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 naturally­occurring 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, central nervous systems, and may have an increased risk of getting cancer.


You do no 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:

The City of Zavalla (City) will clean the interior of the water tower storage tank located at 352 Broaddus Dr. Zavalla, Texas 75980


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 question regarding this matter, you may contact Carlos Guzman at 936-87-3311
