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.

Water source: groundwater (wells)

DAVIS is one of 773 community water systems in Illinois in the 501 to 3,300 people size category, serving 589 people from groundwater.

As of August 1, 2026, its federal record holds 7 entries between 1977 and 2015, all of which EPA lists as closed. Nothing has been added since 2015.

The record involves the Stage 1 Disinfectants and Disinfection Byproducts Rule, the Consumer Confidence Rule, and the Total Coliform Rules.
