MANSFIELD WATER USERS ASSOCIATION is one of 583 community water systems in South Dakota in the 500 or fewer people size category, formerly serving 70 people from groundwater.
EPA's federal records list this system as inactive in 2012; the record below is historical.
As of August 1, 2026, its federal record holds 5 entries between 1976 and 2009, all of which EPA lists as closed. Nothing has been added since 2009.
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 synthetic organic chemicals, the Radionuclides and Revised Rad Rule, and the Stage 1 Disinfectants and Disinfection Byproducts Rule.
