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: 1,200
Service connections: 634

Water source: groundwater (wells)

LAHARPE is one of 773 community water systems in Illinois in the 501 to 3,300 people size category, serving 1,200 people from groundwater.

As of August 1, 2026, its federal record holds 33 entries between 1993 and 2025, of which 1 remains open; none are health-based.
