CATHLAMET WATER DEPT Water System

Consumer Confidence Report status

CATHLAMET WATER DEPT 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 CATHLAMET WATER DEPT.

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.

CATHLAMET WATER DEPT is one of 428 community water systems in Washington in the 501 to 3,300 people size category, serving 1,636 people from surface water.

As of August 1, 2026, its federal record holds 121 entries between 1979 and 2025, all of which EPA lists as closed.

Of the 121, 118 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, inorganic chemicals, and synthetic organic chemicals.

Common questions

Is CATHLAMET WATER DEPT required to publish a Consumer Confidence Report?

Yes. CATHLAMET WATER DEPT 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 CATHLAMET WATER DEPT’s next Consumer Confidence Report due?

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

Does CATHLAMET WATER DEPT have any open drinking water violations on record?

As of August 1, 2026, EPA's federal records show no open violations for CATHLAMET WATER DEPT.

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.
