Portland Harbor is located in and along the Willamette River in Portland, Oregon. More than a century of historical industrial use has resulted in Willamette River sediments being contaminated with many hazardous substances, such as heavy metals, polychlorinated biphenyls (PCBs), polynuclear aromatic hydrocarbons (PAH), dioxin/furans, and pesticides.
Portland Harbor was added to the EPA National Priorities List of contaminated sites in December 2000. The initial focus of the study was the heavily industrialized area between Swan and Sauvie Islands. The investigation area currently extends from the Columbia Slough to the Fremont Bridge.
