Portland Harbor Natural Resource Damage Assessment Data
The Portland Harbor Superfund Site covers an 11 mile stretch of the Lower Willamette River and adjacent floodplains. Since the early 1900s, numerous facilities have released oil, PCBs, heavy metals, pesticides, and other hazardous substances into Portland Harbor. This highly industrialized area of the Willamette River continues to serve as a hub for the commercial shipping industry.
NOAA and other Trustee Council members have been conducting a Natural Resource Damage Assessment (NRDA) since 2010 for the Portland Harbor site, to evaluate natural resource injuries incurred over time in areas contaminated with hazardous substances (such as DDT, PCBs, and others), and oil. More information on the Natural Resource Damage Assessment can be found on the NOAA DARRP website and the Trustee Council website.
