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

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

KOLIGANEK 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.

KOLIGANEK WATER SYSTEM Water System

Consumer Confidence Report status

KOLIGANEK 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 KOLIGANEK 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): AK2260040
System type: Community Water System
Population served: 170
Service connections: 40
Ownership: Native American tribal
Water source: groundwater (wells)

KOLIGANEK WATER SYSTEM is one of 698 community water systems in Alaska in the 500 or fewer people size category, serving 170 people from groundwater.

As of August 1, 2026, its federal record holds 295 entries between 1986 and 2024, of which 1 remains open; none are health-based.

Of the 295, 280 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 Total Coliform Rules.

Common questions

Is KOLIGANEK WATER SYSTEM required to publish a Consumer Confidence Report?: Yes. KOLIGANEK 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 KOLIGANEK WATER SYSTEM’s next Consumer Confidence Report due?: KOLIGANEK WATER SYSTEM’s next Consumer Confidence Report is due by July 1, 2027. The report covers calendar year 2026.
Does KOLIGANEK WATER SYSTEM have any open drinking water violations on record?: As of August 1, 2026, EPA's federal records show 1 item for KOLIGANEK 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.
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.
