Superfund Sites

  • Harbor Oil
    EHAP evaluated the public health significance of exposure to contaminants found at the Harbor Oil Recycling Facility.
  • Portland Harbor
    The Portland Harbor Superfund site is currently considered the portion of the Willamette River that spans from the southern tip of Sauvie Island to the Fremont Bridge. It was proposed for the National Priorities List in late July 2000 and listed in December 2000. This section is the most industrialized segment of the river and also supports heavy marine traffic. EHAP has been asked by the Agency for Toxic Substances and Disease Registry to evaluate the public health significance of exposure to the contaminants of concern, which include PCBs, dioxins, heavy metals, and other hazardous substances.
