Hadley is one of 739 community water systems in Minnesota in the 500 or fewer people size category, serving 56 people from groundwater.
As of August 1, 2026, its federal record holds 6 entries between 2017 and 2022, all of which EPA lists as closed. Nothing has been added since 2022.
All 6 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 Stage 2 Disinfectants and Disinfection Byproducts Rule, and the Lead and Copper Rule.

What is a Consumer Confidence Report?
