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): MT0000187
System type: Community Water System
Population served: 300
Service connections: 98
Ownership: local government
Water source: groundwater (wells)

COOKE CITY WATER DISTRICT is one of 1,084 community water systems in Montana in the 500 or fewer people size category, serving 300 people from groundwater.

As of August 1, 2026, its federal record holds 186 entries between 1996 and 2024, all of which EPA lists as closed.

Of the 186, 171 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, synthetic organic chemicals, and inorganic chemicals.
