Is GRAYHORSE RWD required to publish a Consumer Confidence Report?

Yes. GRAYHORSE RWD 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 GRAYHORSE RWD’s next Consumer Confidence Report due?

GRAYHORSE RWD’s next Consumer Confidence Report is due by July 1, 2027. The report covers calendar year 2026.

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.

GRAYHORSE RWD Water System

Consumer Confidence Report status

GRAYHORSE RWD 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 GRAYHORSE RWD.

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): OK3005717
System type: Community Water System
Population served: 100
Service connections: 108
Ownership: local government
Water source: surface water (rivers, lakes, or reservoirs)

GRAYHORSE RWD is one of 1,277 community water systems in Oklahoma in the 500 or fewer people size category, serving 100 people from surface water.

As of August 1, 2026, its federal record holds 92 entries between 1991 and 2025, all of which EPA lists as closed.

Of the 92, 29 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 Stage 2 Disinfectants and Disinfection Byproducts Rule, the Consumer Confidence Rule, and the Lead and Copper Rule.

EPA’s revised CCR rule takes effect January 1, 2027, and the first reports in the new format are due July 1, 2027.
