Is CARTER CHOUTEAU CO WATER DIST required to publish a Consumer Confidence Report?

Yes. CARTER CHOUTEAU CO WATER DIST 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 CARTER CHOUTEAU CO WATER DIST’s next Consumer Confidence Report due?

CARTER CHOUTEAU CO WATER DIST’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.

System facts

System ID (PWSID): MT0000520
System type: Community Water System
Population served: 150
Service connections: 74
Ownership: local government
Water source: surface water (rivers, lakes, or reservoirs)

CARTER CHOUTEAU CO WATER DIST is one of 1,084 community water systems in Montana in the 500 or fewer people size category, serving 150 people from surface water.

As of August 1, 2026, its federal record holds 100 entries between 1998 and 2026, all of which EPA lists as closed.

Of the 100, 94 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 Surface Water Treatment Rules, and the Total Coliform Rules.
