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.

KOTZEBUE MUN. WATER SYSTEM Water System

Consumer Confidence Report status

KOTZEBUE MUN. WATER 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 KOTZEBUE MUN. WATER 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 Alaska’s official records. Always confirm current status with Alaska before making decisions based on this information.

System facts

System ID (PWSID): AK2340060
System type: Community Water System
Population served: 3,234
Service connections: 777
Ownership: Native American tribal
Water source: surface water (rivers, lakes, or reservoirs)

KOTZEBUE MUN. WATER SYSTEM is one of 109 community water systems in Alaska in the 501 to 3,300 people size category, serving 3,234 people from surface water.

As of August 1, 2026, its federal record holds 204 entries between 1979 and 2026, all of which EPA lists as closed.

Of the 204, 107 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 the Stage 2 Disinfectants and Disinfection Byproducts Rule, volatile organic chemicals, and the Stage 1 Disinfectants and Disinfection Byproducts Rule.
