HOLCOMB PWS is one of 489 community water systems in Missouri in the 501 to 3,300 people size category, serving 635 people from groundwater.
As of August 1, 2026, its federal record holds 13 entries between 2006 and 2025, all of which EPA lists as closed.
Of the 13, 11 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, the Lead and Copper Rule, and the Stage 2 Disinfectants and Disinfection Byproducts Rule.
