Abstract
This study was carried out to evaluate the applicability of the full scale soil washing processes for reducing heavy metal contamination level of soil around an abandoned mine. In the results of soil washing of the target soil with $H_2SO_4$ and NaOH, the As concentrations of treated soil continuously increased compared with contaminated raw soil. Also, removal efficiencies of Zn and Ni were low. This problems might be caused by chemical partitioning of As in soil and its geologic origination, soil particle size, and scale up of washing plant.
