COLUMBUS UTILITIES is one of 102 community water systems in Wisconsin in the 3,301 to 10,000 people size category, serving 5,173 people from groundwater.

As of August 1, 2026, its federal record holds 21 entries between 1991 and 1993, all of which EPA lists as closed. Nothing has been added since 1993.

Of the 21, 20 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, inorganic chemicals, and the Total Coliform Rules.

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.
