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.

ROUNDUP WATER DEPARTMENT is one of 123 community water systems in Montana in the 501 to 3,300 people size category, serving 1,900 people from groundwater.

As of August 1, 2026, its federal record holds 10 entries between 2008 and 2023, all of which EPA lists as closed. Nothing has been added since 2023.

The record involves the Total Coliform Rules, the Consumer Confidence Rule, and the Stage 2 Disinfectants and Disinfection Byproducts Rule.
