SENECA SANITARY DIST NO 1 is one of 1,289 community water systems in Wisconsin in the 500 or fewer people size category, serving 250 people from groundwater.
As of August 1, 2026, its federal record holds 4 entries between 1993 and 1994, all of which EPA lists as closed. Nothing has been added since 1994.
All 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 volatile organic chemicals, the Total Coliform Rules, and synthetic organic chemicals.
