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): MT0000016
System type: Community Water System
Population served: 6,750
Service connections: 2,866
Ownership: local government
Water source: groundwater (wells)

ANACONDA WATER DEPARTMENT is among the 18 largest community water systems in Montana, serving 6,750 people from groundwater.

As of August 1, 2026, its federal record holds 38 entries between 1991 and 2023, all of which EPA lists as closed. Nothing has been added since 2023.

Of the 38, 36 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 Total Coliform Rules, and the Stage 1 Disinfectants and Disinfection Byproducts Rule.
