Yes. Aunuu ASG 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 Aunuu ASG’s next Consumer Confidence Report due?

Aunuu ASG’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.

Aunuu ASG Water System

Consumer Confidence Report status

Aunuu ASG 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 Aunuu ASG.

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 American Samoa’s official records. Always confirm current status with American Samoa before making decisions based on this information.

System facts

System ID (PWSID): AS9310751
System type: Community Water System
Population served: 402
Service connections: 59
Ownership: state government
Water source: groundwater (wells)

Aunuu ASG is one of 94 community water systems in American Samoa in the 500 or fewer people size category, serving 402 people from groundwater.

As of August 1, 2026, its federal record holds 211 entries between 1996 and 2025, all of which EPA lists as closed.

Of the 211, 140 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 Stage 2 Disinfectants and Disinfection Byproducts Rule, the Total Coliform Rules, and synthetic organic chemicals.

Common questions

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