Important Water Quality Alert: TTHM Levels Exceed Safety Standards in Cinco MUD 5 – What You Need to Know

Attention Cinco MUD 5 Residents:

The Texas Commission on Environmental Quality (TCEQ) has issued a notification regarding elevated levels of total trihalomethanes (TTHM) in our drinking water. During 2025 Quarter 1, testing revealed a compliance value of 0.086 mg/L, slightly above the EPA’s Maximum Contaminant Level (MCL) of 0.080 mg/L.

What Are Trihalomethanes (TTHM)?

TTHMs are byproducts formed when chlorine (used for water disinfection) reacts with natural organic matter. While these compounds are common in treated water, prolonged exposure to levels above the MCL may pose health risks, including potential effects on the liver, kidneys, central nervous system, and a possible increased cancer risk.

What Should You Do?

  1. No Immediate Action Required: The water remains safe for general use, but if you have health concerns (e.g., pregnancy, chronic illness), consult your doctor.
  2. Stay Informed: Share this notice with neighbors, especially those in apartments, nursing homes, or schools.
  3. Monitor Updates: Cinco MUD 5 is actively tracking TTHM levels and will provide updates.

Contact & Resources

Your safety is our priority. We’re committed to resolving this issue and ensuring transparent communication.

Note: Repeat notices will be issued every 90 days until compliance is restored. Certificates of delivery are required within 10 days of posting.
