MARSHALL PWS is one of 78 community water systems in Missouri in the 10,001 to 100,000 people size category, serving 12,934 people from groundwater.
As of August 1, 2026, its federal record holds 4 entries between 1991 and 2018, all of which EPA lists as closed. Nothing has been added since 2018.
Of the 4, 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 Total Coliform Rules.
