NAMPA CITY OF is the third largest community water system in Idaho, serving 100,200 people from groundwater.

As of August 1, 2026, its federal record holds 36 entries between 2011 and 2020, all of which EPA lists as closed. Nothing has been added since 2020.

All 36 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 volatile organic chemicals.
