AQUARION-POSSUM RIDGE is one of 799 community water systems in Connecticut in the 500 or fewer people size category, serving 307 people from groundwater.

As of August 1, 2026, its federal record holds 25 entries between 1994 and 2021, all of which EPA lists as closed. Nothing has been added since 2021.

All 25 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 the Radionuclides and Revised Rad Rule, the Lead and Copper Rule, and the Total Coliform Rules.

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.
