Soil pollution around railroad sites is mainly caused by heavy metals and oils. In this study, electrokinetic (EK) remediation was tested to remediate the heavy metal-contaminated railroad soil. The main pollutants of the soil were Cd, Cu, Pb and Zn. The used reactor was 2-D scale and DC electric current was supplied continuously under 2 V/cm. As a result, the total removal efficiency of heavy metals from the contaminated railroad soil was about 55.2 %. In the future, the additional researches are required to enhance the removal efficiency for the residual concentration of heavy metals in soil under the remediation standard levels designated from the Soil Environment Preservation Act in Korea.
