Notice of Drinking Water TOTAL TRIHALOMETHANE Violation
 
The Texas Commission on Environmental Quality (TCEQ) has notified the City of Kerrville water system that the drinking water being supplied to customers had exceeded the Maximum Contaminate Level (MCL) for TOTAL TRIHALOMETHANE (TTHM) during January 2011. The U.S. Environmental Protection Agency (U.S. EPA) has established the MCL for TTHM at 0.080 mg/L, and has determined that it is a health concern at levels above the MCL. Analysis of drinking water in your community for TTHM indicated a level of 0.087 mg/L during January 2011. Some people who drink water containing Trihalomethanes in excess of the MCL over many years may experience problems with their liver, kidneys, 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.
 
The City of Kerrville is actively working on correcting the problem by reducing the TTHM that increased in the distribution system due to the age of the water during January 2011; some of the corrective actions that were taken are:
 
• Painting of storage tanks to lighter colors to lower the temperature of stored water.
• Installing circulation pumps at storage tanks to prevent stratification.
• Changes in treatment chemicals.
• Increased monitoring and sample testing.
• The addition of a new ground water well to blend stored water in Yr-2012.
• Award of a comprehensive engineering study of additional options.

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.
