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

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

MCGRATH 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.

MCGRATH WATER SYSTEM Water System

Consumer Confidence Report status

MCGRATH 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 no open violations for MCGRATH WATER SYSTEM.

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): AK2280155
System type: Community Water System
Population served: 341
Service connections: 150
Ownership: Native American tribal
Water source: surface water (rivers, lakes, or reservoirs)

MCGRATH WATER SYSTEM is one of 698 community water systems in Alaska in the 500 or fewer people size category, serving 341 people from surface water.

As of August 1, 2026, its federal record holds 284 entries between 1985 and 2025, all of which EPA lists as closed.

Of the 284, 225 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, volatile organic chemicals, and the Stage 1 Disinfectants and Disinfection Byproducts Rule.
