Maximum Contaminant Level Violation

Maximum Contaminant Level Violation

MCL, LRAA/TTHM

The Texas Commission on Environmental Quality (TCEQ) has notified the Crystal Farms WSC TX2010012 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 two 2022 of 0.087 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 to get more information about how this may affect you.

We are taking the following actions to address this issue:

In times of high heat we have to add more chlorine to the water to clarify. If we do not do this the result is discolored (brown) water. The use of more chlorine to clarify the water results in a TTHM violation per TCEQ. We are in the process of applying for a grant for a filtration and monitoring system that should work to help clarify the water. Also, because of drought conditions, we were attempting to keep flushing to a minimum to conserve water. We will have to increase flushing.

Please share this information with all people who drink this water, especially those who may not have received this notice directly (ie., 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 Ron Martin at Crystal Farms Water Supply Corporation, (903) 947-2238 or (903) 431-4811.
