CROOKS is one of 124 community water systems in South Dakota in the 501 to 3,300 people size category, serving 1,362 people from groundwater.
As of August 1, 2026, its federal record holds 3 entries between 1976 and 1998, all of which EPA lists as closed. Nothing has been added since 1998.
All 3 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 the Total Coliform Rules.
