An analysis of soils at certain substations operated by Seattle City Light has indicated a number of areas contaminated with polychlorinated biphenyls (PCBs). PCB levels are generally less than 50 ppm in surficial soils. In situ biological treatment technologies have been proven for the degradation of certain waste types (i.e., petrochemical wastes), and published literature has indicated that certain PCB congeners are biodegradable. Our conceptual approach, therefore, will enhance the biomass of indigenous PCB-degrading microbes.
