MOSES COULEE WATER ASSOCIATION Water System

Consumer Confidence Report status

MOSES COULEE 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 MOSES COULEE 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.

MOSES COULEE WATER ASSOCIATION is one of 3,227 community water systems in Washington in the 500 or fewer people size category, serving 42 people from groundwater.

As of August 1, 2026, its federal record holds 117 entries between 1992 and 2019, all of which EPA lists as closed. Nothing has been added since 2019.

Of the 117, 114 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 Total Coliform Rules.

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.
