Is COLCHESTER COMMONS required to publish a Consumer Confidence Report?

Yes. COLCHESTER COMMONS is a community water system, and federal rules (40 CFR 141 Subpart O) require every community water system to publish a Consumer Confidence Report each year.

When is COLCHESTER COMMONS’s next Consumer Confidence Report due?

COLCHESTER COMMONS’s next Consumer Confidence Report is due by July 1, 2027. The report covers calendar year 2026.

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 facts

System ID (PWSID): CT0286011
System type: Community Water System
Population served: 224
Service connections: 96
Ownership: privately owned
Water source: groundwater (wells)

COLCHESTER COMMONS is one of 799 community water systems in Connecticut in the 500 or fewer people size category, serving 224 people from groundwater.

As of August 1, 2026, its federal record holds 83 entries between 1991 and 2024, of which 1 health-based item remains open, alongside 1 other open entry.

Of the 83, 67 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 synthetic organic chemicals, volatile organic chemicals, and the Total Coliform Rules.
