CASITAS DEL MESA MHP is one of 1,084 community water systems in Montana in the 500 or fewer people size category, serving 180 people from groundwater.
As of August 1, 2026, its federal record holds 5 entries between 2013 and 2020, all of which EPA lists as closed. Nothing has been added since 2020.
All 5 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 synthetic organic chemicals and the Radionuclides and Revised Rad Rule.
