Summary

Description

The Cape Romanzof Long Range Radar Site Cape Romanzof contains many petroleumrelated spills and hazardous substances. Therefore, in 1987 and 1988 a field study was conducted by the U.S. Fish and Wildlife Service Service to determine if contaminants from station activities had entered the Yukon Delta National Wildlife Refuges Refuge environment andor trust resources. Analytical results indicate that elevated levels of some polycyclic aromatic hydrocarbons PAHs, organochlorines and trace elements most likely originating from Cape Romanzof are accumulating in wildlife tissue. Most notable were organochlorine compounds in vole, fox and fish samples. Detected were: 1 p,p DDE in all but one sample 0.06 .15 ppm and p,p DDD in vole and fish samples 0.01 0.06 ppm, and 2 total PCBs in all samples voles, 0.95 1.14 ppm; fox adipose fat, 0.58 ppm; fish muscle, 0.16 1.22 ppm. Pathways of uptake include contact, ingestion, or inhalation of contaminated soil, sediment, water, waste or food e.g. fish, small mammals, birds. Sediment samples collected by the Service and water and sediment samples collected by WoodwardClyde Consultants indicate that the Old Landfill is a primary contributor of PAHs, PCBs, chlordane, lead and cadmium contamination.
