ROSEDALE COLONY is one of 583 community water systems in South Dakota in the 500 or fewer people size category, formerly serving 110 people from surface water.
EPA's federal records list this system as inactive in 1993; the record below is historical.
As of August 1, 2026, its federal record holds 2 entries between 1988 and 1992, all of which EPA lists as closed. Nothing has been added since 1992.
Of the 2, 1 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 Radionuclides and Revised Rad Rule and inorganic chemicals.
