Is BERLIN WATER CONTROL COMMISSION required to publish a Consumer Confidence Report?

Yes. BERLIN WATER CONTROL COMMISSION 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 BERLIN WATER CONTROL COMMISSION’s next Consumer Confidence Report due?

BERLIN WATER CONTROL COMMISSION’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): CT0070021
System type: Community Water System
Population served: 5,128
Service connections: 2,557
Ownership: local government
Water source: surface water (rivers, lakes, or reservoirs)

BERLIN WATER CONTROL COMMISSION serves 5,128 people from surface water, placing it in the 3,301 to 10,000 people size category.

As of August 1, 2026, its federal record holds 147 entries between 2003 and 2024, of which 1 health-based item remains open.

Of the 147, 142 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 volatile organic chemicals, the Radionuclides and Revised Rad Rule, and the Stage 2 Disinfectants and Disinfection Byproducts Rule.

Common questions

Is BERLIN WATER CONTROL COMMISSION required to publish a Consumer Confidence Report?: Yes. BERLIN WATER CONTROL COMMISSION 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 BERLIN WATER CONTROL COMMISSION’s next Consumer Confidence Report due?: BERLIN WATER CONTROL COMMISSION’s next Consumer Confidence Report is due by July 1, 2027. The report covers calendar year 2026.
Does BERLIN WATER CONTROL COMMISSION have any open drinking water violations on record?: As of August 1, 2026, EPA's federal records show 1 open health-based violation for BERLIN WATER CONTROL COMMISSION.
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.
