Abstract
This study was performed to evaluate the applicability of pump and treat technology as well as to identify the changes of groundwater level by continuous pumping at the petroleum contaminated site. A total of 9 monitoring wells were installed at the site and the contaminant concentrations, TPH, benzene, toluene, ethylbenzene and xylene, of groundwater were measured. With the results of the groundwater monitoring, a total of 9 wells were set up for pumping contaminated groundwater in 3 locations. The waste water treatment facility with a capacity of $10m^3/hr$ was installed in the site and operated for about 1 year. The concentrations of the contaminated groundwater from the 3 pumping wells were exceeded groundwater regulation for benzene and TPH. However, the effluent concentration of benzene and TPH was under the regulation showing the maximum level of 0.011 mg/L and 1.2 mg/L during the operation periods. Groundwater levels were decreased by continuous pumping and those were not recovered during the operation period. Groundwater levels of PW-1,2, PW-3,4,5,6 and PW-7,8,9 were decreased about 5 m, 0.7 m, 2 m, respectively. The hydraulic conductivity (K) of the region of PW-1,2, PW-3,4,5,6 and PW-7,8,9 was estimated to be $6.143{\times}10^{-5}cm/sec$, $2.675{\times}10^{-5}cm/sec$, $1.198{\times}10^{-4}cm/sec$. Groundwater level was seemed to be affected not by hydraulic conductivity but by morphological effect. These results show that the pump and treat technology has high applicability for the restoration of petroleum contaminated groundwater but needs continuous monitoring to prevent rapid groundwater drawdown.
