DESOTO PWS is one of 140 community water systems in Missouri in the 3,301 to 10,000 people size category, serving 6,400 people from groundwater.
As of August 1, 2026, its federal record holds 3 entries between 2003 and 2005, all of which EPA lists as closed. Nothing has been added since 2005.
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.
