The EPA Explains The Program
The Portland Harbor Superfund Site in Portland is the result of more than a century of industrial use along the Willamette River.
Water and sediments along Portland Harbor are contaminated with many hazardous substances, including heavy metals, polychlorinated biphenyls (PCBs), polynuclear aromatic hydrocarbons (PAH), dioxin, and pesticides. These compounds have been found to be harmful to human health and the environment. Because of the contamination, some types of fish found in Portland Harbor, such as bass, carp and catfish currently pose a health risk to those who eat them.
Portland Harbor was added to EPA's National Priorities List in December 2000. The current study area extends from the Columbia Slough to the Broadway Bridge.
EPA and the Oregon Department of Environmental Quality are working with potentially responsible parties to clean up contaminated sediment and control sources of additional contamination.
