HEBGEN LAKE ESTATES CO WATER SEWER DISTR is one of 1,084 community water systems in Montana in the 500 or fewer people size category, serving 230 people from groundwater.
As of August 1, 2026, its federal record holds 221 entries between 1994 and 2024, all of which EPA lists as closed.
All 221 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, inorganic chemicals, and the Radionuclides and Revised Rad Rule.
