Abstract

Overland flow systems have been proposed as an efficient alternative for the removal of organic pollutants from aqueous waste streams. A simulated wastewater containing polychlorinated biphenyls (PCBs) was added to a model overland flow treatment system. Movement, biodegradation and volatilization of the PCBs were determined in the system using 14C-labeled PCBs and PCB congener-specific, high resolution gas chromatography. PCB removal approached 100% in this system. Movement of PCBs in the soil was minimal with removal occurring primarily in the upper sections of the slope. Mineralization of PCBs was low (≤ 2% of the PCBs added) over the time frame of this experiment. © 1988.
