WESTON MUNICIPAL UTILITIES is one of 87 community water systems in Wisconsin in the 10,001 to 100,000 people size category, serving 16,000 people from groundwater.

As of August 1, 2026, its federal record holds 19 entries between 1994 and 2009, all of which EPA lists as closed. Nothing has been added since 2009.

All 19 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 Radionuclides and Revised Rad Rule, and inorganic chemicals.
