Is CTWC - CRYSTAL SYSTEM required to publish a Consumer Confidence Report?

Yes. CTWC - CRYSTAL SYSTEM 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 CTWC - CRYSTAL SYSTEM’s next Consumer Confidence Report due?

CTWC - CRYSTAL SYSTEM’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.

CTWC - CRYSTAL SYSTEM Water System

Consumer Confidence Report status

CTWC - CRYSTAL SYSTEM must publish a Consumer Confidence Report — the annual drinking water quality report covering calendar year 2026 — by July 1, 2027.

As of August 1, 2026, EPA's federal records show no open violations for CTWC - CRYSTAL SYSTEM.

Data sourced from the EPA ECHO database (SDWA bulk download), last refreshed August 1, 2026. This is a record-keeping and public-information tool — it does not replace Connecticut’s official records. Always confirm current status with Connecticut before making decisions based on this information.

System facts

System ID (PWSID): CT0690011
System type: Community Water System
Population served: 6,378
Service connections: 2,909
Ownership: privately owned
Water source: groundwater (wells)

CTWC - CRYSTAL SYSTEM serves 6,378 people from groundwater, placing it in the 3,301 to 10,000 people size category.

As of August 1, 2026, its federal record holds 94 entries between 1989 and 2018, all of which EPA lists as closed. Nothing has been added since 2018.

Of the 94, 87 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, synthetic organic chemicals, and the Radionuclides and Revised Rad Rule.

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.
