WINCHESTER WATER DEPT is one of 969 community water systems in Idaho in the 500 or fewer people size category, serving 400 people from groundwater.
As of August 1, 2026, its federal record holds 4 entries between 1979 and 2020, all of which EPA lists as closed. Nothing has been added since 2020.
All 4 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 the Radionuclides and Revised Rad Rule, the Lead and Copper Rule, and the Total Coliform Rules.
