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): IL1090350
System type: Community Water System
Population served: 15,051
Service connections: 5,551
Ownership: local government
Water source: surface water (rivers, lakes, or reservoirs)

MACOMB is one of 225 community water systems in Illinois in the 10,001 to 100,000 people size category, serving 15,051 people from surface water.

As of August 1, 2026, its federal record holds 31 entries between 1977 and 2024, of which 1 remains open; none are health-based.

Of the 31, 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 Surface Water Treatment Rules, the Stage 1 Disinfectants and Disinfection Byproducts Rule, and the Stage 2 Disinfectants and Disinfection Byproducts Rule.
