Mandatory Language for a Maximum Contaminant Level Violation

Mandatory Language for a Maximum Contaminant Level Violation

MCL, AVERAGE / ARSENIC

The Texas Commission on Environmental Quality (TCEQ) has notified the Ellinger Sewer and WSC,
TX0750014, public water system that the drinking water being supplied to customers had exceeded the
Maximum Contaminant Level (MCL) for arsenic. The U.S. Environmental Protection Agency (U.S. EPA)
has established the MCL for arsenic to be 0.010 milligrams per liter (mg/L) based on the running annual
average (RAA), and has determined that it is a health concern at levels above the MCL.
Analysis of drinking water in your community for arsenic indicates a compliance value in Quarter 4
2024 of 0.012 mg/L for EP001.
This is not an emergency. However, some people who drink water containing arsenic in excess of the
MCL over many years could experience skin damage or problems with their circulatory system, 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 following actions were taken to address this issue: The water plant with arsenic removal system
came online on January 29, 2025. This will reduce the amount of arsenic below the MCL and bring the
public water supply system back into compliance.
