VALLEY GROVE SUBDIVISION is one of 123 community water systems in Montana in the 501 to 3,300 people size category, serving 825 people from groundwater.

As of August 1, 2026, its federal record holds 38 entries between 1994 and 2020, all of which EPA lists as closed. Nothing has been added since 2020.

Of the 38, 25 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 Consumer Confidence Rule, the Total Coliform Rules, and inorganic chemicals.

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.
