GREGORY is one of 124 community water systems in South Dakota in the 501 to 3,300 people size category, serving 1,221 people from groundwater.
As of August 1, 2026, its federal record holds 5 entries between 1976 and 2005, all of which EPA lists as closed. Nothing has been added since 2005.
All 5 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 Radionuclides and Revised Rad Rule, and the Lead and Copper Rule.
