WADENA WATER SYSTEM is one of 1,221 community water systems in Iowa in the 500 or fewer people size category, serving 209 people from groundwater.
As of August 1, 2026, its federal record holds 3 entries between 1980 and 2018, all of which EPA lists as closed. Nothing has been added since 2018.
Of the 3, 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 Groundwater Rule, the Total Coliform Rules, and inorganic chemicals.
