LONG LAKE COLONY is one of 583 community water systems in South Dakota in the 500 or fewer people size category, serving 100 people from groundwater.
As of August 1, 2026, its federal record holds 3 entries between 1993 and 2012, all of which EPA lists as closed. Nothing has been added since 2012.
Of the 3, 2 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 and synthetic organic chemicals.
