Lake Quinault Water System

Consumer Confidence Report status

Lake Quinault 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 Lake Quinault.

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

Lake Quinault is one of 428 community water systems in Washington in the 501 to 3,300 people size category, serving 1,003 people from groundwater.

As of August 1, 2026, its federal record holds 265 entries between 1979 and 2007, all of which EPA lists as closed. Nothing has been added since 2007.

Of the 265, 264 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 inorganic chemicals.

Common questions

Is Lake Quinault required to publish a Consumer Confidence Report?

Yes. Lake Quinault 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 Lake Quinault’s next Consumer Confidence Report due?

Lake Quinault’s next Consumer Confidence Report is due by July 1, 2027. The report covers calendar year 2026.

Does Lake Quinault have any open drinking water violations on record?

As of August 1, 2026, EPA's federal records show no open violations for Lake Quinault.

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.
