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.

TROY PWS is one of 78 community water systems in Missouri in the 10,001 to 100,000 people size category, serving 15,000 people from groundwater.

As of August 1, 2026, its federal record holds 9 entries between 1980 and 2012, all of which EPA lists as closed. Nothing has been added since 2012.

The record involves the Radionuclides and Revised Rad Rule, the Total Coliform Rules, and the Consumer Confidence Rule.
