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.

ARAPAHO is one of 511 community water systems in Oklahoma in the 501 to 3,300 people size category, serving 748 people from surface water.

As of August 1, 2026, its federal record holds 14 entries between 2004 and 2025, all of which EPA lists as closed.

All 14 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 Stage 1 Disinfectants and Disinfection Byproducts Rule, and the Stage 2 Disinfectants and Disinfection Byproducts Rule.
