WASHINGTON PWS is one of 78 community water systems in Missouri in the 10,001 to 100,000 people size category, serving 14,068 people from groundwater.
As of August 1, 2026, its federal record holds 16 entries between 1992 and 2025, of which 1 remains open; none are health-based.
Of the 16, 4 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 Stage 2 Disinfectants and Disinfection Byproducts Rule, and the Lead and Copper Rule.
