KALISPELL PUBLIC WORKS is among the 8 largest community water systems in Montana, serving 25,000 people from groundwater.
As of August 1, 2026, its federal record holds 47 entries between 1996 and 2020, all of which EPA lists as closed. Nothing has been added since 2020.
Of the 47, 45 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 volatile organic chemicals, synthetic organic chemicals, and inorganic chemicals.
