NEZPERCE WATER DEPT is one of 969 community water systems in Idaho in the 500 or fewer people size category, serving 460 people from groundwater.
As of August 1, 2026, its federal record holds 5 entries in 1979, all of which EPA lists as closed. Nothing has been added since 1979.
All 5 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 inorganic chemicals and the Radionuclides and Revised Rad Rule.
