OUZINKIE WATER SYSTEM Water System
Consumer Confidence Report status
OUZINKIE 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 1 item for OUZINKIE WATER SYSTEM 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.

OUZINKIE WATER SYSTEM is one of 698 community water systems in Alaska in the 500 or fewer people size category, serving 144 people from surface water.
As of August 1, 2026, its federal record holds 204 entries between 1979 and 2026, of which 1 remains open; none are health-based.
Of the 204, 167 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, synthetic organic chemicals, and inorganic chemicals.

Common questions
Is OUZINKIE WATER SYSTEM required to publish a Consumer Confidence Report?
- Yes. OUZINKIE 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 OUZINKIE WATER SYSTEM’s next Consumer Confidence Report due?
- OUZINKIE WATER SYSTEM’s next Consumer Confidence Report is due by July 1, 2027. The report covers calendar year 2026.
Does OUZINKIE WATER SYSTEM have any open drinking water violations on record?
- As of August 1, 2026, EPA's federal records show 1 item for OUZINKIE WATER SYSTEM 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.
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.
