Is KOBUK WATER SYSTEM required to publish a Consumer Confidence Report?

Yes. KOBUK WATER 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 KOBUK WATER SYSTEM’s next Consumer Confidence Report due?

KOBUK WATER 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.

KOBUK WATER SYSTEM Water System

Consumer Confidence Report status

KOBUK 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 1 item for KOBUK WATER SYSTEM that is open and awaiting resolution. None are health-based violations — open items of this kind are most often monitoring or reporting requirements, not water-safety findings.

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): AK2340565
System type: Community Water System
Population served: 93
Service connections: 31
Ownership: Native American tribal
Water source: groundwater (wells)

KOBUK WATER SYSTEM is one of 698 community water systems in Alaska in the 500 or fewer people size category, serving 93 people from groundwater.

As of August 1, 2026, its federal record holds 349 entries between 1985 and 2026, of which 1 remains open; none are health-based.

Of the 349, 305 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, the Groundwater Rule, and volatile organic chemicals.
