MOSCOW WATER DEPT is among the 11 largest community water systems in Idaho, serving 26,000 people from groundwater.
As of August 1, 2026, its federal record holds 4 entries between 2018 and 2021, all of which EPA lists as closed. Nothing has been added since 2021.
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 volatile organic chemicals and the Total Coliform Rules.
