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.

WELLS GARDEN ESTATES is one of 1,084 community water systems in Montana in the 500 or fewer people size category, serving 240 people from groundwater.

As of August 1, 2026, its federal record holds 45 entries between 1997 and 2023, all of which EPA lists as closed. Nothing has been added since 2023.
