Greenleafton is one of 739 community water systems in Minnesota in the 500 or fewer people size category, serving 140 people from groundwater.
As of August 1, 2026, its federal record holds 13 entries between 2007 and 2025, all of which EPA lists as closed.
All 13 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, the Lead and Copper Rule, and inorganic chemicals.
