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.

System facts

System ID (PWSID): OK1011101
System type: Community Water System
Population served: 1,649
Service connections: 856
Ownership: local government
Water source: surface water (rivers, lakes, or reservoirs)

COMANCHE PUBLIC WORKS AUTHORITY is one of 511 community water systems in Oklahoma in the 501 to 3,300 people size category, serving 1,649 people from surface water.

As of August 1, 2026, its federal record holds 98 entries between 2004 and 2025, all of which EPA lists as closed.

Of the 98, 15 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 Stage 1 Disinfectants and Disinfection Byproducts Rule, and the Surface Water Treatment Rules.
