Is UNIFIED ALASKAN UTILITIES SHERWOOD ESTAT required to publish a Consumer Confidence Report?

Yes. UNIFIED ALASKAN UTILITIES SHERWOOD ESTAT 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 UNIFIED ALASKAN UTILITIES SHERWOOD ESTAT’s next Consumer Confidence Report due?

UNIFIED ALASKAN UTILITIES SHERWOOD ESTAT’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.

UNIFIED ALASKAN UTILITIES SHERWOOD ESTAT Water System

Consumer Confidence Report status

UNIFIED ALASKAN UTILITIES SHERWOOD ESTAT 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 UNIFIED ALASKAN UTILITIES SHERWOOD ESTAT 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): AK2224078
System type: Community Water System
Population served: 147
Service connections: 59
Ownership: privately owned
Water source: groundwater (wells)

UNIFIED ALASKAN UTILITIES SHERWOOD ESTAT is one of 698 community water systems in Alaska in the 500 or fewer people size category, serving 147 people from groundwater.

As of August 1, 2026, its federal record holds 292 entries between 1988 and 2025, of which 1 remains open; none are health-based.

Of the 292, 276 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, synthetic organic chemicals, and the Total Coliform Rules.
