PIONEER PARK CO-OP INC Water System
Consumer Confidence Report status
PIONEER PARK CO-OP INC 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 1 item for PIONEER PARK CO-OP INC that is open and awaiting resolution. None are health-based violations — open items of this kind are most often monitoring or reporting requirements, not water-safety findings.
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 Oregon’s official records. Always confirm current status with Oregon before making decisions based on this information.

PIONEER PARK CO-OP INC is one of 1,168 community water systems in Oregon in the 500 or fewer people size category, serving 54 people from groundwater.
As of August 1, 2026, its federal record holds 39 entries between 1976 and 2025, of which 1 remains open; none are health-based.
Of the 39, 29 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, the Total Coliform Rules, and the Groundwater Rule.
