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.

CORDOVA is one of 773 community water systems in Illinois in the 501 to 3,300 people size category, serving 640 people from groundwater.

As of August 1, 2026, its federal record holds 19 entries between 1977 and 2025, all of which EPA lists as closed.

Of the 19, 17 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, the Stage 1 Disinfectants and Disinfection Byproducts Rule, and the Total Coliform Rules.
