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): IL1150150
System type: Community Water System
Population served: 76,122
Service connections: 31,407
Ownership: local government
Water source: surface water (rivers, lakes, or reservoirs)

DECATUR is among the 15 largest community water systems in Illinois, serving 76,122 people from surface water.

As of August 1, 2026, its federal record holds 21 entries between 1977 and 2023, all of which EPA lists as closed. Nothing has been added since 2023.

Of the 21, 2 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 inorganic chemicals, the Surface Water Treatment Rules, and the Stage 1 Disinfectants and Disinfection Byproducts Rule.
