The Texas Commission on Environmental Quality (TCEQ) has notified the CITY OF ANNONA
TX1940004 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 quarter three 2026 of 0.094 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 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.
We are taking the following actions to address this issue: The City plans to review the elevated
TTHM results with its water operator and TCEQ, investigate possible causes, evaluate appropriate
corrective measures, and continue required monitoring. These actions are planned and do not
indicate that the violation has been resolved.
Please share this information with all the 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 questions regarding this matter, you may contact the City of Annona at (903) 697-3581.
