OSCEOLA PWS is one of 489 community water systems in Missouri in the 501 to 3,300 people size category, serving 947 people from groundwater.
As of August 1, 2026, its federal record holds 8 entries between 2010 and 2017, all of which EPA lists as closed. Nothing has been added since 2017.
All 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 Total Coliform Rules and the Lead and Copper Rule.
