The Portland Harbor [Oregon]Superfund Site includes an in-river and an upland portion of the lower Willamette River, contaminated from decades of industrial use along the Willamette River. The Portland Harbor Superfund Site was added to EPA’s National Priorities List in December 2000.

Water and sediment at the Portland Harbor Site are contaminated with many hazardous substances, including polychlorinated biphenyls (PCBs), polycyclic aromatic hydrocarbons (PAHs), dioxins/furans, pesticides and heavy metals. These compounds have been found to be harmful to people and the environment. Health risks at the site are great enough for cleanup to be needed under the Superfund law.

The Willamette River is an integral feature of the Portland, Oregon metropolitan area, which is home to over 500,000 people. The harbor is an international portal for commerce; dozens of industries within the site provide economic sustainability to the community. The Lower Willamette is also a popular area for recreation, including fishing and boating. The river provides a critical migratory corridor and rearing habitat for salmon and steelhead, including endangered runs of steelhead and chinook. The area holds great importance to several tribes as a natural and cultural resource.

“Mr. Spadaro will briefly present about his experience at the Portland Harbor Superfund Site including information on the site history, sediment characteristics, remedial design, and project cost allocation.”
