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.

HAMILTON MOBILE VILLAGE is one of 1,084 community water systems in Montana in the 500 or fewer people size category, serving 53 people from groundwater.

As of August 1, 2026, its federal record holds 74 entries between 1981 and 2017, all of which EPA lists as closed. Nothing has been added since 2017.

The record involves volatile organic chemicals, synthetic organic chemicals, and the Total Coliform Rules.
