GRACEVALE COLONY is one of 583 community water systems in South Dakota in the 500 or fewer people size category, formerly serving 100 people from groundwater.
EPA's federal records list this system as inactive in 1999; the record below is historical.
As of August 1, 2026, its federal record holds 10 entries between 1991 and 1997, all of which EPA lists as closed. Nothing has been added since 1997.
Of the 10, 9 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 Total Coliform Rules, volatile organic chemicals, and inorganic chemicals.
