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): MT0000021
System type: Community Water System
Population served: 1,858
Service connections: 876
Ownership: local government
Water source: groundwater (wells)

BAKER CITY OF is one of 123 community water systems in Montana in the 501 to 3,300 people size category, serving 1,858 people from groundwater.

As of August 1, 2026, its federal record holds 120 entries between 1997 and 2025, all of which EPA lists as closed.

Of the 120, 110 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, the Stage 2 Disinfectants and Disinfection Byproducts Rule, and the Consumer Confidence Rule.
