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.

QUAPAW TRIBE is one of 1,277 community water systems in Oklahoma in the 500 or fewer people size category, serving 55 people from groundwater.

As of August 1, 2026, its federal record holds 30 entries between 1992 and 2024, all of which EPA lists as closed.

Of the 30, 25 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 Total Coliform Rules, the Lead and Copper Rule, and the Stage 1 Disinfectants and Disinfection Byproducts Rule.
