Osseo is one of 330 community water systems in Minnesota in the 501 to 3,300 people size category, serving 2,650 people from groundwater.
As of August 1, 2026, its federal record holds 2 entries between 2018 and 2020, all of which EPA lists as closed. Nothing has been added since 2020.
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 Stage 1 Disinfectants and Disinfection Byproducts Rule.
