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): KY0530083
System type: Community Water System
Population served: 300
Service connections: 99
Ownership: local government
Water source: groundwater (wells)

COLUMBUS WATER WORKS is one of 353 community water systems in Kentucky in the 500 or fewer people size category, serving 300 people from groundwater.

As of August 1, 2026, its federal record holds 143 entries between 1982 and 2024, all of which EPA lists as closed.

Of the 143, 132 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 inorganic chemicals.

Common questions

Is COLUMBUS WATER WORKS required to publish a Consumer Confidence Report?: Yes. COLUMBUS WATER WORKS 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 COLUMBUS WATER WORKS’s next Consumer Confidence Report due?: COLUMBUS WATER WORKS’s next Consumer Confidence Report is due by July 1, 2027. The report covers calendar year 2026.
Does COLUMBUS WATER WORKS have any open drinking water violations on record?: As of August 1, 2026, EPA's federal records show no open violations for COLUMBUS WATER WORKS.
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.
