PORT WING SANITARY DISTRICT is one of 1,289 community water systems in Wisconsin in the 500 or fewer people size category, serving 400 people from groundwater.

As of August 1, 2026, its federal record holds 22 entries between 1993 and 2014, all of which EPA lists as closed. Nothing has been added since 2014.

Of the 22, 21 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 inorganic chemicals.
