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): IL1115600
System type: Community Water System
Population served: 485
Service connections: 194
Ownership: privately owned
Water source: groundwater (wells)

AQUA ILLINOIS-NUNDA is one of 1,572 community water systems in Illinois in the 500 or fewer people size category, serving 485 people from groundwater.

As of August 1, 2026, its federal record holds 52 entries between 1977 and 2016, all of which EPA lists as closed. Nothing has been added since 2016.

Of the 52, 46 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 synthetic organic chemicals, the Total Coliform Rules, and the Lead and Copper Rule.
