The Portland Harbor Superfund Site in Portland, Oregon is located in the lower Willamette River, just south of the Columbia Slough (river mile 1.9) and north of the Broadway Bridge (river mile 11.8). Portland Harbor has a long history of shipping, industrial, and commercial activity because of its key location on the Willamette River. This area of the river also has historical, natural and cultural resource significance.

Map of the Portland Harbor cleanup area

A joint U.S. Environmental Protection Agency (EPA) and Oregon Department of Environmental Quality (DEQ) study in 1997 showed that river sediments in Portland Harbor are contaminated with DDT and other pesticides, polychlorinated biphenyls (PCBs), and petroleum. Based on this information, EPA designated Portland Harbor as a Superfund Site in December 2000.

This is an unusually complicated Superfund site, one of the most complex in the EPA Superfund program. The site:

  • Has been subject to decades of historical contamination with a variety of pollutants
  • Involves numerous potentially responsible parties
  • Has endangered species act (ESA) considerations
  • Is culturally significant to six Native American tribes.

The EPA on January 6, 2017 issued its final cleanup plan. See the City's response.
