THORP WATERWORKS is one of 333 community water systems in Wisconsin in the 501 to 3,300 people size category, serving 1,636 people from groundwater.

As of August 1, 2026, its federal record holds 7 entries between 1994 and 2024, all of which EPA lists as closed.

Of the 7, 6 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 Lead and Copper Rule, the Radionuclides and Revised Rad Rule, and the Public Notice Rule and Revised PN Rule.

It lists the contaminants detected in the system’s water during the year, where the water comes from, and how the results compare with federal limits. EPA’s revised CCR rule takes effect January 1, 2027, and the first reports in the new format are due July 1, 2027.
