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): OK1020708
System type: Community Water System
Population served: 13,495
Service connections: 4,800
Ownership: local government
Water source: surface water (rivers, lakes, or reservoirs)

OKMULGEE PWA is one of 56 community water systems in Oklahoma in the 10,001 to 100,000 people size category, serving 13,495 people from surface water.

As of August 1, 2026, its federal record holds 212 entries between 1993 and 2026, all of which EPA lists as closed.

Of the 212, 74 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 volatile organic chemicals.

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