GASCONADE PWS is one of 1,412 community water systems in Missouri in the 500 or fewer people size category, serving 280 people from groundwater.
As of August 1, 2026, its federal record holds 14 entries between 1993 and 2023, all of which EPA lists as closed. Nothing has been added since 2023.
Of the 14, 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 the Consumer Confidence Rule, the Total Coliform Rules, and the Lead and Copper Rule.
