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 type: Community Water System
Population served: 843
Service connections: 337
Ownership: local government
Water source: groundwater (wells)

HARDIN COUNTY WATER DISTRICT NO.1 is one of 773 community water systems in Illinois in the 501 to 3,300 people size category, serving 843 people from groundwater.

As of August 1, 2026, its federal record holds 35 entries between 1977 and 2003, all of which EPA lists as closed. Nothing has been added since 2003.
