CAPITOL WATER CORP is one of 32 community water systems in Idaho in the 3,301 to 10,000 people size category, serving 9,000 people from groundwater.
As of August 1, 2026, its federal record holds 39 entries between 1992 and 2025, all of which EPA lists as closed.
All 39 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, the Total Coliform Rules, and volatile organic chemicals.
