SOUTHERN WISCONSIN CENTER is one of 333 community water systems in Wisconsin in the 501 to 3,300 people size category, serving 950 people from groundwater.

As of August 1, 2026, its federal record holds 15 entries between 1983 and 2026, all of which EPA lists as closed.

Of the 15, 12 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 Radionuclides and Revised Rad Rule, the Total Coliform Rules, and the Stage 2 Disinfectants and Disinfection Byproducts Rule.
