AYERS HUTTERITE COLONY is one of 1,084 community water systems in Montana in the 500 or fewer people size category, serving 58 people from groundwater.
As of August 1, 2026, its federal record holds 10 entries between 2007 and 2020, all of which EPA lists as closed. Nothing has been added since 2020.
Of the 10, 4 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.
