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 ID (PWSID): CT0606011
System type: Community Water System
Population served: 27
Service connections: 9
Ownership: privately owned
Water source: groundwater (wells)

QUONNIPAUG HILLS - SECTION I is one of 799 community water systems in Connecticut in the 500 or fewer people size category, serving 27 people from groundwater.

As of August 1, 2026, its federal record holds 44 entries between 1990 and 2018, all of which EPA lists as closed. Nothing has been added since 2018.

The record involves volatile organic chemicals, the Total Coliform Rules, and the Consumer Confidence Rule.
