HOLDEN PWS is one of 489 community water systems in Missouri in the 501 to 3,300 people size category, serving 2,683 people from surface water.
As of August 1, 2026, its federal record holds 5 entries between 2006 and 2022, all of which EPA lists as closed. Nothing has been added since 2022.
Of the 5, 3 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 synthetic organic chemicals, the Stage 2 Disinfectants and Disinfection Byproducts Rule, and inorganic chemicals.
