Site summary

Portland Harbor is a heavily industrialized stretch of the Lower Willamette River north of downtown Portland, from Sauvie Island south to the Broadway Bridge. EPA listed Portland Harbor on the National Priorities List, known as Superfund, in December 2000. Sediments in the river are contaminated with various toxic compounds, including metals, polycyclic aromatic hydrocarbons, polychlorinated biphenyls (known as PCBs), chlorinated pesticides and dioxin. Levels of these pollutants in the river appear to be highest near contaminated sites on the shore, known as upland sites.


EPA, DEQ and other agencies, tribal governments, community groups and companies are working to investigate and clean up contamination in Portland Harbor. EPA is the lead agency responsible for investigating and cleaning up contaminated sediments in the river itself. DEQ is the lead agency for investigating and cleaning up contamination on upland sites, working with individual property owners. Both EPA and DEQ coordinate with six Tribal governments and other natural resource trustees. The Portland Harbor Natural Resource Trustee Council is designated by law to act on behalf of the public or Tribes to protect and manage natural resources.
