Source Water Assessment Results for Public Water Systems Using Surface Water 

  • To view the summary report for a completed Source Water Assessment, click on the PWS Number (i.e. 41xxxxx) on the left side of the table below. Additional information is available in the full Source Water Assessment Report. To obtain a copy of the Source Water Assessment Report:
    • Contact your PWS owner/operator to review the full report or get a copy. Information for PWSs including the contact person is available in both the Upstream PWSs and Downstream PWSs Report links (below) or at the Oregon Health Authority Drinking Water Program website (see "Drinking Water Data Online").
    • DEQ and OHA also have copies of Source Water Assessment reports.

      For groundwater system reports, contact Drue Edney, OHA, at 541-726-2587 ext. 25 or by email.

      For surface water systems, contact Julie Harvey, DEQ, at 503-229-5664 or by email.

  • Instructions on how to view and identify source water areas using DEQ's Facility Profiler

  • Upstream/Downstream PWS Report links: For watersheds with more than one intake, Oregon completes the assessments by segment and each Source Water Assessment represents the area from the PWS's intake to the next intake upstream. A list of water systems that are upstream or downstream of any given intake are provided in the See Report link below. All protection areas for intakes upstream of the PWS's intake are included in its drinking water protection area. Activities and impacts in the protection area for upstream water users also have the potential to impact downstream water users. We encourage the water providers and communities within each watershed to work together as you move forward with developing strategies or a protection plan.


  • For PWSs that use both surface water and groundwater, the summary reports below only address the surface water component of the drinking water supply.
