On Dec. 30, 2016, the Nueces County Judge, two County Commissioners, County Attorney, and State Representative Herrero met with the water supplier and Texas Commission on Environmental Quality (TCEQ), related to rural resident water. Locally, we will stay working on this issue until it is resolved and will continue to ensure the water is safe for the public to consume. Judge Neal appreciates the help of State Representative Herrero in facilitating the collaboration between the TCEQ and local officials.
The TCEQ has provided the following statement:
“Water from Nueces Water Supply Corporation (WSC) is safe to consume. You do not need to use an alternative water supply. As of December 30, 2016 Nueces Water Supply Corporation (WSC) has one total trihalomethanes (TTHM) maximum contaminant level (MCL) violation for fourth (October-December) quarter 2016 and provided public notice per drinking water regulations. The WSC exceeded the 0.080 milligrams per liter (mg/L) TTHM MCL with a compliance average of 0.083 mg/L. For these levels at short durations exposure should not be expected to cause health effects.
MCLs for a chemical that is known or suspected to cause adverse health effects from long-term exposure, such as TTHM, is based upon people drinking two liters (about half a gallon) of water a day for seventy years (approximately one lifetime).
TTHMs are a group of volatile organic compounds that are formed when disinfectants, such as chlorine and chloramine, are added to water during the treatment process and react with naturally-occurring organic matter in the water.
Nueces WSC has communicated to the TCEQ that they have implemented a number of strategies to reduce TTHM formation. These include use of a flow switch to control the injection of the chlorine disinfection system, flushing distribution lines, and studying aeration as a long-term TTHM removal strategy.
TCEQ will continue to oversee the WSC’s compliance with the drinking water standards.”
We will continue to keep the public informed on this issue.
