Windom is one of 90 community water systems in Minnesota in the 3,301 to 10,000 people size category, serving 4,646 people from groundwater.
As of August 1, 2026, its federal record holds 2 entries between 2007 and 2019, all of which EPA lists as closed. Nothing has been added since 2019.
All 2 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 Lead and Copper Rule and the Total Coliform Rules.
