Is KASAAN required to publish a Consumer Confidence Report?

Yes. KASAAN 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 KASAAN’s next Consumer Confidence Report due?

KASAAN’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.

KASAAN Water System

Consumer Confidence Report status

KASAAN 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 KASAAN.

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): AK2120606
System type: Community Water System
Population served: 66
Service connections: 39
Ownership: Native American tribal
Water source: surface water (rivers, lakes, or reservoirs)

KASAAN is one of 698 community water systems in Alaska in the 500 or fewer people size category, serving 66 people from surface water.

As of August 1, 2026, its federal record holds 188 entries between 1988 and 2025, all of which EPA lists as closed.

Of the 188, 136 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 Surface Water Treatment Rules, the Stage 1 Disinfectants and Disinfection Byproducts Rule, and volatile organic chemicals.

Common questions

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