Is Chilchinbeto Community Day School BIA required to publish a Consumer Confidence Report?

Yes. Chilchinbeto Community Day School BIA is a community water system, and federal rules (40 CFR 141 Subpart O) require every community water system to publish a Consumer Confidence Report each year.

When is Chilchinbeto Community Day School BIA’s next Consumer Confidence Report due?

Chilchinbeto Community Day School BIA’s next Consumer Confidence Report is due by July 1, 2027. The report covers calendar year 2026.

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.

Data sourced from the EPA ECHO database (SDWA bulk download), last refreshed August 1, 2026.

System facts

System ID (PWSID): NN0433002
System type: Community Water System
Population served: 138
Service connections: 15
Ownership: federal government
Water source: groundwater (wells)

Chilchinbeto Community Day School BIA is one of 125 community water systems in Navajo Nation in the 500 or fewer people size category, serving 138 people from groundwater.

As of August 1, 2026, its federal record holds 74 entries between 2004 and 2025, all of which EPA lists as closed.

Of the 74, 71 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, volatile organic chemicals, and the Stage 1 Disinfectants and Disinfection Byproducts Rule.
