About

The Portland Harbor Superfund Site Interim Data Portal provides public access to view and download analytical data and reports associated with environmental studies of 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.

This data portal has been established to meet the immediate need for data sharing as parties begin to design cleanup actions for the Portland Harbor Superfund Site. In the future, EPA anticipates working with cleanup parties to stand up a more comprehensive information platform that will allow users to interact more easily with environmental data from the Portland Harbor Superfund Site.
