August 2026 · Orevant Compliance Intelligence
Texas has more than 7,000 public water systems — the most of any state. The Texas Commission on Environmental Quality (TCEQ) enforces the Safe Drinking Water Act alongside Texas Administrative Code Chapter 290. In 2026, PFAS deadlines, LCRR inventory requirements, and ongoing monitoring obligations create a demanding compliance calendar.
All Texas public water systems must comply with TCEQ Chapter 290. TCEQ conducts sanitary surveys every 3 to 5 years and deficiencies carry formal corrective action timelines.
Texas community water systems must complete initial PFAS monitoring by April 2027. The EPA sets MCLs of 4 ppt for PFOA and PFOS. Detections above the MCL require public notification within 30 days.
Texas systems must build and submit a complete lead service line inventory to TCEQ. Systems with lead lines must follow the federal replacement schedule. Texas has significant numbers of older distribution systems where service line materials are unknown.
Texas community water systems must deliver a CCR by July 1 each year. TCEQ requires Spanish-language notifications in many service areas.
Texas systems issuing Boil Water Notices must follow TCEQ Tier 1 notification requirements within 24 hours. Failure to notify is a separate violation from the underlying issue.
