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.

Population served: 9,506

ITASCA is one of 248 community water systems in Illinois in the 3,301 to 10,000 people size category, serving 9,506 people from surface water.

As of August 1, 2026, its federal record holds 6 entries between 1977 and 2018, all of which EPA lists as closed. Nothing has been added since 2018.

Of the 6, 5 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 Total Coliform Rules, and the Lead and Copper Rule.
