Yes. NULATO RIVER WELL 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 NULATO RIVER WELL’s next Consumer Confidence Report due?

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.

Consumer Confidence Report status

NULATO RIVER WELL 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 NULATO RIVER WELL.

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): AK2360785
System type: Community Water System
Population served: 245
Service connections: 70
Ownership: Native American tribal
Water source: groundwater (wells)

NULATO RIVER WELL is one of 698 community water systems in Alaska in the 500 or fewer people size category, serving 245 people from groundwater.

As of August 1, 2026, its federal record holds 156 entries between 1993 and 2025, all of which EPA lists as closed.

Of the 156, 148 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 volatile organic chemicals, the Total Coliform Rules, and the Lead and Copper Rule.

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