CHATTANOOGA PWS Water System
Consumer Confidence Report status
CHATTANOOGA PWS must publish a Consumer Confidence Report — the annual drinking water quality report covering calendar year 2026 — by July 1, 2027.
As of August 1, 2026, EPA's federal records show no open violations for CHATTANOOGA PWS.
Data sourced from the EPA ECHO database (SDWA bulk download), last refreshed August 1, 2026. This is a record-keeping and public-information tool — it does not replace Oklahoma’s official records. Always confirm current status with Oklahoma before making decisions based on this information.

CHATTANOOGA PWS is one of 511 community water systems in Oklahoma in the 501 to 3,300 people size category, serving 627 people from groundwater.
As of August 1, 2026, its federal record holds 68 entries between 1997 and 2024, all of which EPA lists as closed.
Of the 68, 66 are monitoring and reporting requirements — the category that accounts for about four in five of all violations in EPA's national dataset — rather than findings about the water itself. The record involves volatile organic chemicals, the Radionuclides and Revised Rad Rule, and the Lead and Copper Rule.

Common questions
Is CHATTANOOGA PWS required to publish a Consumer Confidence Report?
- Yes. CHATTANOOGA PWS is a community water system, and federal rules (40 CFR 141 Subpart O) require every community water system to publish a Consumer Confidence Report each year.
When is CHATTANOOGA PWS’s next Consumer Confidence Report due?
- CHATTANOOGA PWS’s next Consumer Confidence Report is due by July 1, 2027. The report covers calendar year 2026.
Does CHATTANOOGA PWS have any open drinking water violations on record?
- As of August 1, 2026, EPA's federal records show no open violations for CHATTANOOGA PWS.
What is a Consumer Confidence Report?
- A Consumer Confidence Report (CCR) is the annual drinking water quality report that community water systems must provide to the people they serve. It lists the contaminants detected in the system’s water during the year, where the water comes from, and how the results compare with federal limits. EPA’s revised CCR rule takes effect January 1, 2027, and the first reports in the new format are due July 1, 2027.
