CLARKSVILLE PWS is one of 1,412 community water systems in Missouri in the 500 or fewer people size category, serving 442 people from groundwater.
As of August 1, 2026, its federal record holds 7 entries between 1981 and 2023, all of which EPA lists as closed. Nothing has been added since 2023.
Of the 7, 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 Radionuclides and Revised Rad Rule, and the Stage 1 Disinfectants and Disinfection Byproducts Rule.
