WINFRED WATER DISTRICT INC is one of 583 community water systems in South Dakota in the 500 or fewer people size category, formerly serving 60 people from groundwater.
EPA's federal records list this system as inactive in 2008; the record below is historical.
As of August 1, 2026, its federal record holds 5 entries between 1976 and 1979, all of which EPA lists as closed. Nothing has been added since 1979.
All 5 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 inorganic chemicals and the Radionuclides and Revised Rad Rule.
