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.

HILLSIDE HOMES is one of 1,084 community water systems in Montana in the 500 or fewer people size category, serving 35 people from groundwater.

As of August 1, 2026, its federal record holds 10 entries between 1993 and 2023, all of which EPA lists as closed. Nothing has been added since 2023.
