Oregon's Source Water Assessment Results and Maps

Maps of the groundwater and surface water drinking water source areas and potential contaminant sources identified within those drinking water source areas are available as GIS data layers and in a print-ready format. Due to security reasons, the agencies are restricting access to the GIS layers with latitude/longitude readings of wells, springs and intakes. Maps and assessment results can be downloaded here or are available on the Oregon Geospatial Enterprise Office's data clearinghouse web site under Drinking Water. If you do not find what you are looking for or would like individual maps, data layers or data queries at a local or regional scale, please contact DEQ's GIS Specialist at 503-229-6883 or by email.
