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.

Water source: groundwater (wells)

MINONK is one of 773 community water systems in Illinois in the 501 to 3,300 people size category, serving 1,928 people from groundwater.

As of August 1, 2026, its federal record holds 11 entries between 1977 and 2002, all of which EPA lists as closed. Nothing has been added since 2002.

Of the 11, 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 Radionuclides and Revised Rad Rule, volatile organic chemicals, and the Lead and Copper Rule.
