HENRY is one of 583 community water systems in South Dakota in the 500 or fewer people size category, serving 256 people from groundwater.
As of August 1, 2026, its federal record holds 6 entries between 1976 and 2025, all of which EPA lists as closed.
All 6 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 Stage 1 Disinfectants and Disinfection Byproducts Rule, the Total Coliform Rules, and the Radionuclides and Revised Rad Rule.
