PIONEER Water System
Consumer Confidence Report status
PIONEER 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 PIONEER.
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.

PIONEER is one of 3,227 community water systems in Washington in the 500 or fewer people size category, serving 84 people from groundwater.
As of August 1, 2026, its federal record holds 298 entries between 2006 and 2007, all of which EPA lists as closed. Nothing has been added since 2007.
Of the 298, 296 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 synthetic organic chemicals, volatile organic chemicals, and the Total Coliform Rules.

Common questions
Is PIONEER required to publish a Consumer Confidence Report?
- Yes. PIONEER 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 PIONEER’s next Consumer Confidence Report due?
- PIONEER’s next Consumer Confidence Report is due by July 1, 2027. The report covers calendar year 2026.
Does PIONEER have any open drinking water violations on record?
- As of August 1, 2026, EPA's federal records show no open violations for PIONEER.
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.
