Case Study on Remediation of Petroleum Contaminated Groundwater and Soil in Kangwon Province, Korea
The aim of this study is to examine actual conditions of contamination and current situations of remediation for a petroleum contaminated site (formerly military facility) in Kangwon province, Korea. Bedrock of the study area is metamorphic rocks which originated the Pre-Cambrian sedimentary rocks and it was intruded by Jurassic granites. Above them, the Quaternary alluvium unconformably overlies. The alluvium consists of sand or granule and top surface is covered by reclamation soil for construction. Groundwater in the study area was contaminated by unsuitable management or accidental spill of petroleum storages, thus the contaminated area was distributed around the petroleum storage tanks. 7.5% of the study area was contaminated by the petroleum hydrocarbons. Chemical analyses revealed that the groundwater in the study area was contaminated with TPH (Total Petroleum Hydrocarbon), TCE (Trichloroethylene), PCE (Tetrachloroethylene) and MTBE (Methyl Tertiary-Butyl Ether). In case of TPH, maximum value was 708.9 mg/L in 2005 and 93.8 mg/L in 2008. TCE was 0.002 mg/L in 2005 and 0.104 mg/L in 2008. PCE was 0.027 mg/L in 2005 and 0.139 mg/L in 2008. A 78~100 cm thickness of free phase oil was detected in 2005. In 2008, free phase oil was detected at less than 1 cm thickness. In-situ and ex-situ remediation technologies have been applied to remove the contaminants in the study area. Considering the study areas current situation such as geologic characteristics of the study area, distribution of contaminants and remediation schedule, it is expected that ex-situ technology is more efficient than in-situ technique in the study area. Pump and treat, soil washing, landfarming and low temperature thermal desorption are expected to be efficient way to clean up the contaminated soil and groundwater. The study area will be used for citizens such as dwellings, parks and gyms when the remediation is completed. This study reports on the contamination status of groundwater and soil and remediation processes for cleaning up them.
