Health assessment for Harbor Island Lead, Seattle, King County, Washington, Region 10. CERCLIS No. WAD980722839. Preliminary report

Technical Report ·
OSTI ID:5049861

The Harbor Island Lead site is on the National Priorities List. Harbor Island is a 405-acre island that was constructed during the early 1900s in an area consisting of inter-tidal wetlands at the mouth of the Duwamish River and Elliott Bay. The extent of environmental contamination on Harbor Island has not been described. Environmental contamination in surface sediments and polychlorinated biphenyl (PCB) concentrations in Elliott Bay fish has been provided. Sediments are contaminated with heavy metals, including antimony (91,370 ppm), arsenic (584 ppm), chromium (1,0080 ppm), lead (71,100 ppm), manganese (3,390 ppm), nickel (366 ppm), and zinc (6,010 ppm); polynuclear aromatic hydrocarbons (PAHs) (3,800 ppm), including benzo(a)pyrene (100 ppm), fluoranthene (1,300 ppm), phenanthrene (330 ppm), and pyrene (740 ppm); various pesticides (0.9 ppm total); and phenols (10 ppm), including pentachlorophenol (6 ppm). The site is considered to be of potential public health concern because it appears that the most important pathway is ingestion of contaminated fish and shellfish.
