CHENOA is one of 773 community water systems in Illinois in the 501 to 3,300 people size category, serving 1,785 people from groundwater.

As of August 1, 2026, its federal record holds 24 entries between 1977 and 2025, of which 1 remains open; none are health-based.

Of the 24, 11 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 Stage 2 Disinfectants and Disinfection Byproducts Rule, the Lead and Copper Rule, and the Radionuclides and Revised Rad 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.
