This website provides public access to view and download analytical data and reports associated with environmental studies of the Portland Harbor Superfund Site. All data sets and associated reports available through this website have been approved by EPA to use in designing future cleanup actions for the Portland Harbor Superfund Site. The Portland Harbor Superfund Site includes the lower Willamette River near Portland, Oregon, from river mile 1.9 to river mile 11.8. When available, reports associated with data collection and analysis may also be viewed and downloaded for each study. Additional data sets will be added to this site as they become available. EPA is continuing to explore more comprehensive approaches for managing and displaying data for the Portland Harbor Superfund Site.
