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): IL1977210
System type: Community Water System
Population served: 312
Service connections: 104
Ownership: privately owned
Water source: groundwater (wells)

AQUA ILLINOIS-OAKVIEW is one of 1,572 community water systems in Illinois in the 500 or fewer people size category, serving 312 people from groundwater.

As of August 1, 2026, its federal record holds 52 entries between 1977 and 2025, all of which EPA lists as closed.

Of the 52, 36 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 volatile organic chemicals, the Radionuclides and Revised Rad Rule, and the Total Coliform Rules.
