MARIONVILLE is one of 489 community water systems in Missouri in the 501 to 3,300 people size category, serving 2,092 people from groundwater.
As of August 1, 2026, its federal record holds 3 entries between 1993 and 2007, all of which EPA lists as closed. Nothing has been added since 2007.
Of the 3, 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 Total Coliform Rules.
