WINDY ACRES WUA is one of 1,084 community water systems in Montana in the 500 or fewer people size category, serving 50 people from groundwater.

As of August 1, 2026, its federal record holds 9 entries between 1995 and 2023, all of which EPA lists as closed. Nothing has been added since 2023.

Of the 9, 6 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 the Radionuclides and Revised Rad Rule, the Total Coliform Rules, and inorganic chemicals.

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.
