Mountain Iron is one of 330 community water systems in Minnesota in the 501 to 3,300 people size category, serving 2,880 people from groundwater.
As of August 1, 2026, its federal record holds 2 entries in 2021, all of which EPA lists as closed. Nothing has been added since 2021.
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 Total Coliform Rules and the Stage 1 Disinfectants and Disinfection Byproducts Rule.
