ABSTRACT:
A method and apparatus for treating polychlorinated biphenyl (PCB) contaminated soil includes providing a contaminated soil having PCBs therein and treating the soil with elemental zinc powder. The elemental zinc powder reacts with the PCBs in the contaminated soil to at least partially dechlorinate the PCB component of the soil. Also provide are means for treating the PCB contaminated soil including grinding means for achieving a preferred size range for the soil and mixing means to provide intimate contact between the contaminated soil and elemental zinc powder. The method may be practice in-situ such that the PCB contaminated soil is treated at a soil site containing the PCB contaminants.
