The Portland Harbor Superfund Site in Portland, Oregon, 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.
Current status: We're working with the Lower Willamette Group to finalize the draft ecological risk assessment, remedial investigation and the feasibility study which evaluates cleanup alternatives for Portland Harbor. We will use the final remedial investigation and feasibility study to develop a proposed cleanup plan by 2014. When released there will be a series of public information sessions to discuss the proposed plan and the opportunity for formal public comments. Until then, we will continue to meet with the community to provide updates, answer questions, and listen to concerns.
