Public Notice (TTHM)

Mandatory Language for a Maximum Contaminant Level Violation MCL, LRAA / TTHM

The Texas Commission on Environmental Quality (TCEQ) has notified North Runnels Water Supply Corporation (WSC) that the drinking water being supplies to customers had exceeded the Maximum Contaminant Level (MCL) for total trihalomethanes  to be 0.080 milligrams per liter (mg/L) based on locational running annual average (LRAA) and has been determined this 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 2021 of 0.108 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 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 are working with TRWA, monitoring water quality daily.  Flushing dead end mains weekly to address this issue.

Please share this information with all the other people who drink this water, especially those who may not have received this notice directly (for example, 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.
