SPEARFISH is among the 12 largest community water systems in South Dakota, serving 13,803 people from groundwater.
As of August 1, 2026, its federal record holds 3 entries between 1976 and 1995, all of which EPA lists as closed. Nothing has been added since 1995.
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 inorganic chemicals.
