Is NORTHERN KENTUCKY WATER DISTRICT required to publish a Consumer Confidence Report?

Yes. NORTHERN KENTUCKY WATER DISTRICT 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 NORTHERN KENTUCKY WATER DISTRICT’s next Consumer Confidence Report due?

NORTHERN KENTUCKY WATER DISTRICT’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.

NORTHERN KENTUCKY WATER DISTRICT Water System

Consumer Confidence Report status

NORTHERN KENTUCKY WATER DISTRICT 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 NORTHERN KENTUCKY WATER DISTRICT.

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 Kentucky’s official records. Always confirm current status with Kentucky before making decisions based on this information.

System facts

System ID (PWSID): KY0590220
System type: Community Water System
Population served: 259,949
Service connections: 90,310
Ownership: local government
Water source: surface water (rivers, lakes, or reservoirs)

NORTHERN KENTUCKY WATER DISTRICT is the third largest community water system in Kentucky, serving 259,949 people from surface water.

As of August 1, 2026, its federal record holds 140 entries between 1993 and 2016, all of which EPA lists as closed. Nothing has been added since 2016.

All 140 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 Stage 1 Disinfectants and Disinfection Byproducts Rule.

EPA’s revised CCR rule takes effect January 1, 2027, and the first reports in the new format are due July 1, 2027.
