00354 PFAS Sample Results | Data Online | Oregon Drinking Water Services

More Information: PFAS Rule Information & Sampling Project
Abbreviations: MCL = Maximum contaminant level, MRL = Minimum reporting level, ND = Not detected at the minimum reporting level, PFAS = Per- and polyfluoroalkyl substances. Analytes with an MCL are in bold. Sample results detected above the MCL are in bold red.
Water systems must be in compliance with the MCL by 2029. Sample results can be used for compliance when their MRL meets the requirements of the PFAS rule. Results that cannot be used for compliance are shaded gray and italicized.

Initial Monitoring

This water system is part of the OHA PFAS Sampling Project. DEQ will collect the first sample from each active entry point by the end of July 2026. The water system is responsible for collecting additional samples needed to meet the initial monitoring requirements.
EP ID	Entry point name	Water type	Availability	Frequency	Schedule begin	Schedule end	First quarter or First sample	Second quarter or Second sample	Third quarter	Fourth quarter
EP-A	EP FOR WELLS #1, #2 & #3	GW	Permanent	2 samples	1/1/2023		12/9/2025		N/A	N/A
For each active entry point served by groundwater, collect 2 consecutive samples within a 12-month period with samples collected 5 to 7 months apart.
