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): OK2006362
System type: Community Water System
Population served: 5,172
Service connections: 2,332
Ownership: local government
Water source: groundwater (wells)

TRI-COUNTY RWD #2 is one of 106 community water systems in Oklahoma in the 3,301 to 10,000 people size category, serving 5,172 people from groundwater.

As of August 1, 2026, its federal record holds 40 entries between 1995 and 2024, all of which EPA lists as closed.

Of the 40, 36 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 inorganic chemicals, the Total Coliform Rules, and the Radionuclides and Revised Rad Rule.
