CULBERTSON TOWN OF is one of 123 community water systems in Montana in the 501 to 3,300 people size category, serving 714 people from surface water.
As of August 1, 2026, its federal record holds 19 entries between 1993 and 2018, all of which EPA lists as closed. Nothing has been added since 2018.
All 19 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 Lead and Copper Rule, and the Total Coliform Rules.
