FONTANA WATER UTILITY is one of 333 community water systems in Wisconsin in the 501 to 3,300 people size category, serving 1,839 people from groundwater.

As of August 1, 2026, its federal record holds 7 entries between 1999 and 2025, of which 1 remains open; none are health-based.

Of the 7, 4 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, synthetic organic chemicals, and the Public Notice Rule and Revised PN Rule.

What is a Consumer Confidence Report?

A Consumer Confidence Report (CCR) is the annual drinking water quality report that community water systems must provide to the people they serve. 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.
