DELTA WATER ASSOCIATION Water System

Consumer Confidence Report status

DELTA WATER ASSOCIATION 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 DELTA WATER ASSOCIATION.

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.

DELTA WATER ASSOCIATION is one of 3,227 community water systems in Washington in the 500 or fewer people size category, serving 450 people from groundwater.

As of August 1, 2026, its federal record holds 150 entries between 1979 and 2024, all of which EPA lists as closed.

Of the 150, 95 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 inorganic chemicals, synthetic organic chemicals, and volatile organic chemicals.

What is a Consumer Confidence Report?

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.
