PLATTE is one of 124 community water systems in South Dakota in the 501 to 3,300 people size category, serving 1,256 people from surface water.
As of August 1, 2026, its federal record holds 2 entries between 2009 and 2023, all of which EPA lists as closed. Nothing has been added since 2023.
Of the 2, 1 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 2 Disinfectants and Disinfection Byproducts Rule and the Lead and Copper Rule.
