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.

CICERO is among the 12 largest community water systems in Illinois, serving 83,000 people from surface water.

As of August 1, 2026, its federal record holds 10 entries between 1992 and 2026, of which 3 remain open; none are health-based.

Of the 10, 7 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 Total Coliform Rules, the Lead and Copper Rule, and the Stage 1 Disinfectants and Disinfection Byproducts Rule.
