COLLINS COLONY is one of 583 community water systems in South Dakota in the 500 or fewer people size category, serving 95 people from groundwater.
As of August 1, 2026, its federal record holds 12 entries between 2019 and 2022, all of which EPA lists as closed. Nothing has been added since 2022.
All 12 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, synthetic organic chemicals, and the Radionuclides and Revised Rad Rule.
