OPHEIM TOWN OF is one of 1,084 community water systems in Montana in the 500 or fewer people size category, serving 111 people from surface water.

As of August 1, 2026, its federal record holds 42 entries between 1995 and 2021, all of which EPA lists as closed. Nothing has been added since 2021.

Of the 42, 28 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 inorganic chemicals, the Total Coliform Rules, and synthetic organic chemicals.
