AMITY SQUARE WATER SYSTEM 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 51 entries between 1997 and 2014, all of which EPA lists as closed. Nothing has been added since 2014.

Of the 51, 49 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 volatile organic chemicals, synthetic organic chemicals, and inorganic chemicals.
