Mandatory Language for a Maximum Contaminant Level Violation - TTHM
The Texas Commission on Environmental Quality (TCEQ) has notified The Consolidated WSC Central System public water system 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 a 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 2 of 0.089 mg/L for DBP2-02, and 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:
This notice DOES NOT apply to most customers, refer to the bottom of this notice page for a map of impacted areas and corresponding corrective measures. This issue is transitory and primarily limited to surface water (lake water). Flash flooding, high temperatures, and water age significantly reduce the quality of water sourced from lakes. Our corrective measures include switching to well water, working with our vendor to optimize lake water treatment and distribution, and reducing water age through increased flushing activities.
- Green Highlighted Areas: Pipeline Rd. area, downtown Latexo to FM 2022 area, and the Hwy 21 area between the loop and CR 1515. This area was switched to well water from a new well before this exceedance was detected. Your water meets TCEQ and EPA safe drinking water standards but may feel, smell or taste slightly different. These aesthetic issues will continually improve with use.
- Yellow Highlighted Areas: Spring Creek Country Club area out to FM 229 in Wheeler Springs. This area was switched to well water that meets TCEQ and EPA safe drinking water standards on July 15, 2024. You may notice softness, color, taste or odor changes which will continually improve with use. Lynette Lane area: We are planning a line extension to supply your area with well water. This will reverse flow and create temporary color, odor and taste issues which will continually improve with use. The expected time to complete this project is August 30, 2024.
- Red Highlighted Areas: Loop 304, limited sections of FM 229, Halls Bluff, 7W, 21W, 2110, 19S, 4020 and connecting roads. Well water is not immediately accessible. We are planning the significant line construction and easement work needed to send well water to your area in the future. In the meantime, we are flushing to reduce water age and working with our vendor, Houston County WCID 1, to optimize treatment.
- If your service area is not shown or highlighted: There have been no significant changes to your water. You are on well water that meets TCEQ and EPA safe drinking water standards and may disregard this notice.
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 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 Amber Stelly or John Owens at 936-544-2986.
