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): NN0400209
System type: Community Water System
Population served: 496
Service connections: 145
Ownership: Native American tribal
Water source: groundwater (wells)

White Mesa NTUA is one of 125 community water systems in Navajo Nation in the 500 or fewer people size category, serving 496 people from groundwater.

As of August 1, 2026, its federal record holds 46 entries between 2008 and 2024, all of which EPA lists as closed.

All 46 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 volatile organic chemicals, the Stage 2 Disinfectants and Disinfection Byproducts Rule, and the Lead and Copper Rule.
