Groundwater Protection and Well Stewardship

Oregon's Domestic Well Safety Program

DWSP logo

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.
