Wyoming is one of 90 community water systems in Minnesota in the 3,301 to 10,000 people size category, serving 3,990 people from groundwater.
As of August 1, 2026, its federal record holds 1 entry in 2007, all of which EPA lists as closed. Nothing has been added since 2007.
All 1 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 Total Coliform Rules.
