BARABOO WATERWORKS is one of 87 community water systems in Wisconsin in the 10,001 to 100,000 people size category, serving 12,703 people from groundwater.
As of August 1, 2026, its federal record holds 13 entries between 2006 and 2020, all of which EPA lists as closed. Nothing has been added since 2020.
All 13 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 Stage 1 Disinfectants and Disinfection Byproducts Rule, and the Stage 2 Disinfectants and Disinfection Byproducts Rule.
