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): IL2010350
System type: Community Water System
Population served: 7,685
Service connections: 2,275
Ownership: local government
Water source: groundwater (wells)

ROCKTON is one of 248 community water systems in Illinois in the 3,301 to 10,000 people size category, serving 7,685 people from groundwater.

As of August 1, 2026, its federal record holds 39 entries between 1977 and 2025, all of which EPA lists as closed.

Of the 39, 9 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 Radionuclides and Revised Rad Rule, the Total Coliform Rules, and the Public Notice Rule and Revised PN Rule.
