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: 2,753
Service connections: 1,328
Ownership: local government
Water source: surface water (rivers, lakes, or reservoirs)

HAMILTON is one of 773 community water systems in Illinois in the 501 to 3,300 people size category, serving 2,753 people from surface water.

As of August 1, 2026, its federal record holds 12 entries between 1977 and 1997, all of which EPA lists as closed. Nothing has been added since 1997.

Of the 12, 8 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 Total Coliform Rules, and the Radionuclides and Revised Rad Rule.
