What this does not mean

  • —Violations do not indicate current non-compliance. A health-based violation that is marked resolved means the utility has returned to compliance per EPA records. Historic violations are shown for transparency, not to imply ongoing risk.
  • —PFAS detections above MRL are not themselves violations. UCMR 5 monitoring is a surveillance program. Detection does not mean the utility violated a regulation. The 2024 EPA PFAS rule (MCLs for PFOA, PFOS, etc.) has a compliance deadline of 2029.
  • —This page does not assess health risk. WaterUtilityReport.com presents official government records — we do not make health risk determinations, safety certifications, or compliance judgments. Consult a licensed water quality specialist or physician for health advice.
  • —Records may be incomplete. EPA SDWIS and UCMR 5 represent what was reported to the EPA. Not all utilities or contaminants are covered. Small systems (<10,000 people) may not have been required to participate in UCMR 5 monitoring.

Independent Verification

Get your water tested by a certified lab

EPA compliance data shows what utilities report to regulators. An independent test from a certified laboratory confirms what is actually coming out of your tap at the point of use. Labs in Texas can test for PFAS (EPA Method 533 or 537.1), lead, nitrates, bacteria, and more.
