| Short Description |
Water and sediment samples collected from six drainage basins below Paine Field, an airport and industrial/small business complex near Everett, Washington, were analyzed for the EPA priority pollutants/hazardous substances list compounds and subjected to 48-hour bioassays with Daphnia pulex (water samples) and 10-day bioassays with Hyalella azteca (sediment samples).

| Abstract | Long Description |
Water and sediment samples collected from six drainage basins below Paine Field, an airport and industrial/small business complex near Everett, Washington, were analyzed for the EPA priority pollutants/hazardous substances list compounds and subjected to 48-hour bioassays with Daphnia pulex (water samples) and 10-day bioassays with Hyalella azteca (sediment samples). Several instances of potentially significant chemical contamination were identified, the most noteworthy being a high concentration of PCB-1254 (20,500 ug/Kg, dry weight) in sediments at the outlet of a retention pond at the Boeing Commercial Airplane Company facility. Bioassays indicated most drainage water sediments were non-toxic. Paine Field drainage did not appear to be an important source of chemical contamination to adjacent waters of Puget Sound. |
