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, LCRI inventory requirements (November 1, 2027 compliance date), and ongoing monitoring obligations create a demanding compliance calendar.

TCEQ Chapter 290

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.

PFAS — Initial Monitoring by 2027

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.

Lead and Copper Rule Improvements (LCRI)

The LCRI compliance date is November 1, 2027. 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.

Consumer Confidence Report

Texas community water systems must deliver a CCR by July 1 each year. TCEQ requires Spanish-language notifications in many service areas.

Boil Water Notices

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.

FAQ

Does Orevant cover TCEQ rules, not just federal EPA?

Yes. Texas-specific TCEQ Chapter 290 requirements are included alongside all applicable federal EPA standards.

How current is the data?

Search uses a local SDWIS mirror, re-synced monthly. Live records are pulled at scan time. Federal databases can trail state files by a quarter or more; reports disclose that lag.

What if my system serves a small rural community?

Orevant is built for small systems. Small rural Texas systems often have the most complex compliance situations relative to staff capacity.
