The Texas Commission on Environmental Quality (TCEQ) is an environmental agency that protects Texas’ public health and natural resources, including clean air, clean water, and the safe management of waste. TCEQ has established regulations that water systems, including Texas Water Utilities, are required to follow. We regularly monitor for a number of water quality factors and report findings to TCEQ.
Texas Water Utilities is required to share all notices of violation with our customers, which are sent with your next bill following a violation.
Notice: Mandatory Language for a Maximum Contaminant Level Violation MCL, LRAA/TTHM
Provided to: Inverness Point, Pine Harbor
Date: February 2023
What does it mean?
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. A running average of each quarter’s samples determines the Maximum Contaminant Level of trihalomethanes.
As a public water system, Texas Water Utilities is required to monitor for several contaminants to ensure drinking water does not exceed Maximum Contaminant Levels. In the notice delivered to customers in February 2023, TCEQ determined that the running annual average (RAA) of trihalomethanes in drinking water supplied by us exceeded the Maximum Contaminant Level of 0.080 milligrams per liter (mg/L) by a very narrow margin of 0.001 mg/L in Q4 2022 at Inverness Point Water System and by 0.027 in Q4 2022 and Q4 2023.
