WATER DISTRICT 19 Water System

Consumer Confidence Report status

WATER DISTRICT 19 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 WATER DISTRICT 19.

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.

WATER DISTRICT 19 is one of 112 community water systems in Washington in the 3,301 to 10,000 people size category, serving 5,335 people from surface water.

As of August 1, 2026, its federal record holds 123 entries between 1979 and 2025, all of which EPA lists as closed.

Of the 123, 119 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 the Surface Water Treatment Rules.

Common questions

Is WATER DISTRICT 19 required to publish a Consumer Confidence Report?

Yes. WATER DISTRICT 19 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 WATER DISTRICT 19’s next Consumer Confidence Report due?

WATER DISTRICT 19’s next Consumer Confidence Report is due by July 1, 2027. The report covers calendar year 2026.

Does WATER DISTRICT 19 have any open drinking water violations on record?

As of August 1, 2026, EPA's federal records show no open violations for WATER DISTRICT 19.

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.
