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): OK2003518
System type: Community Water System
Population served: 420
Service connections: 207
Ownership: local government
Water source: groundwater (wells)

WAPANUCKA is one of 1,277 community water systems in Oklahoma in the 500 or fewer people size category, serving 420 people from groundwater.

As of August 1, 2026, its federal record holds 48 entries between 1994 and 2021, all of which EPA lists as closed. Nothing has been added since 2021.

Of the 48, 43 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 synthetic organic chemicals, the Total Coliform Rules, and the Consumer Confidence Rule.
