Exceeds Trihalomethane Limits
City of Rosebud 07/10/2017
Maximum Contaminant Level Violation MCL, LRAA/TTHM
The Texas Commission on Environmental Quality (TCEQ) has notified CITY OF ROSEBUD TX0730003 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) base on locational running annual
average (LRAA), and has determined that 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 2017 of 0.139 mg/L for DBP2-02 and 0.103 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 address this issue:
CENTRAL TEXAS WATER SUPPLY has informed the City of Rosebud that the test taken and performed on May 15, 2017 was during the “burn out” being conducted by CTWS and stated that this “burn out” procedure would cause the results of the test to run high. We have been assured by CTWS that all levels are back to normal.
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
business). You can do this by posting this notice in a public place or distributing copies by hand
