COTTONWOOD GROVE MOBILE HOME PARK is one of 583 community water systems in South Dakota in the 500 or fewer people size category, formerly serving 30 people from surface water.
EPA's federal records list this system as inactive in 2025; the record below is historical.
As of August 1, 2026, its federal record holds 14 entries between 2004 and 2023, all of which EPA lists as closed. Nothing has been added since 2023.
Of the 14, 11 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 Stage 2 Disinfectants and Disinfection Byproducts Rule, and the Public Notice Rule and Revised PN Rule.
