THOMPSON RANCHETTES II is one of 1,084 community water systems in Montana in the 500 or fewer people size category, serving 100 people from groundwater.
As of August 1, 2026, its federal record holds 28 entries between 1996 and 2020, all of which EPA lists as closed. Nothing has been added since 2020.
Of the 28, 24 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 Consumer Confidence Rule.
