Bench-scale tests were conducted to investigate the feasibility of a two phase detoxification process that would have application to the treatment of soils contaminated with polychlorinated biphenyls (PCBs) abd 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD). The first of the process was to degrade the contaminants by using Ultraviolet (UV) radiation facilitated by the addition of a surfactant to mobilize contaminants. Biological degradation, the second step, was then used to further detoxify the soil. Results from UV testing indicated that there was no apparent destruction of the dioxin on the soil. PCB reductions ranged from less than 15% to 69%.
