| Abstract | Long Description |
Possible sources of PCBs to Hylebos Waterway were investigated by sampling sediment deposits at 43 sites in or near discharges to the waterway. Total PCB concentrations ranged from less than 13 to 31,000 ug/kg dry weight (dw). An "action criterion" of 1000 ug/kg total PCBs/kg dw was established at the beginning of the study to identify samples which required further investigation. Based on this criterion, three locations were identified as potential PCB sources of concern to Hylebos Waterway: General Metals (21,000 – 31,000 ug/kg dw); Occidental Seep #1 (1,800 estimated ug/kg dw); and Locomotive Yard Channels (1,500 ug/kg dw). Samples of suspended particulate matters (SPM) were also collected from saltwater intakes and process effluents at two industrial sites. PCBs were detected only in SPM samples from the saltwater intake at Pennwalt Chemical Corporation (100 ug/kg dw). |
