PRAIRIE ACRES SOUTH is one of 583 community water systems in South Dakota in the 500 or fewer people size category, serving 170 people from groundwater.
As of August 1, 2026, its federal record holds 16 entries between 1976 and 2015, all of which EPA lists as closed. Nothing has been added since 2015.
Of the 16, 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 volatile organic chemicals, the Stage 1 Disinfectants and Disinfection Byproducts Rule, and the Radionuclides and Revised Rad Rule.
