LANTERN ESTATES is one of 583 community water systems in South Dakota in the 500 or fewer people size category, serving 192 people from groundwater.
As of August 1, 2026, its federal record holds 13 entries between 1976 and 2008, all of which EPA lists as closed. Nothing has been added since 2008.
Of the 13, 8 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 Consumer Confidence Rule, the Total Coliform Rules, and inorganic chemicals.
