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.

System facts

System ID (PWSID): IL0290250
System type: Community Water System
Population served: 19,500
Service connections: 8,000
Ownership: local government
Water source: surface water (rivers, lakes, or reservoirs)

MATTOON is one of 225 community water systems in Illinois in the 10,001 to 100,000 people size category, serving 19,500 people from surface water.

As of August 1, 2026, its federal record holds 14 entries between 1979 and 2010, all of which EPA lists as closed. Nothing has been added since 2010.

Of the 14, 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 Surface Water Treatment Rules, inorganic chemicals, and the Stage 1 Disinfectants and Disinfection Byproducts Rule.
