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.

Consumer Confidence Report status

WELCH PWA 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 WELCH PWA.

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.

System facts

System ID (PWSID): OK2001801
System type: Community Water System
Population served: 800
Service connections: 406
Ownership: local government
Water source: groundwater (wells)

WELCH PWA is one of 511 community water systems in Oklahoma in the 501 to 3,300 people size category, serving 800 people from groundwater.

As of August 1, 2026, its federal record holds 48 entries between 1991 and 2025, all of which EPA lists as closed.

Of the 48, 31 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 the Radionuclides and Revised Rad Rule, synthetic organic chemicals, and volatile organic chemicals.

Common questions

Is WELCH PWA required to publish a Consumer Confidence Report?: Yes. WELCH PWA 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 WELCH PWA’s next Consumer Confidence Report due?: WELCH PWA’s next Consumer Confidence Report is due by July 1, 2027. The report covers calendar year 2026.
Does WELCH PWA have any open drinking water violations on record?: As of August 1, 2026, EPA's federal records show no open violations for WELCH PWA.
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.
