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.

MONTGOMERY is one of 225 community water systems in Illinois in the 10,001 to 100,000 people size category, serving 28,956 people from groundwater.

As of August 1, 2026, its federal record holds 9 entries between 1977 and 2023, all of which EPA lists as closed. Nothing has been added since 2023.

The record involves the Radionuclides and Revised Rad Rule, synthetic organic chemicals, and the Total Coliform Rules.
