Approximately 23% of Oregonians rely on domestic wells, or private wells, as their primary source of potable water.
This makes groundwater protection and well stewardship of high public health importance. To protect both the lifelong health of Oregonians and the state’s groundwater resources, the Oregon Domestic Well Safety Program (DWSP) focuses on improving local and state capacity to assess and manage risks associated with private wells. DWSP partners with local health departments and water information providers to further promote domestic well safety.
      • *NEW* Resource-Sampling Guide...The DWSP now has an updated Sampling document available. This 'How to' guide provides step by step instructions on how to sample your water for routine testing. If your laboratory does not provide instructions, use this one-page Sampling Guide!

      • DWSP will provide one award each of $5k to support capacity building of domestic well safety outreach, during the period of January 1, 2015 through August 31, 2015. The application process was competitive and DWSP thanks all other applicants for their submissions.
