Abstract
The partitioning tracer method has been studied in geoenvironmental field as an alternative method for estimating the quantity of nonaqueous phase liquids(NAPLs) in contaminated subsurface. The subsurface contamination by petroleum, which is a kind of light-nonaqueous phase liquid(LNAPLs), is commonly occurred for spills and leaks of petroleum-based liquids from under storage tank. In this study, the quantity of petroleum contamination in subsurface was estimated using partitioning tracer method under one dimensional column experiment. Partitioning tracers and a nonpartitioning tracer were injected at one time into petroleum contaminated column for a certain period and the chloride ion was used as nonpartitioning tracer and the several types of alcohol were used as partitioning tracer. The partitioning tracers retarded in soil column contaminated by petroleum with respect to their partition coefficient between petroleum and water. The higher partition coefficient was, the more partitioning tracer retarded in petroleum contaminated soil column. As a result of analyzing this retardation by first moment method, the quantity of petroleum in the soil column were estimated. It was found that using two partitioning tracers was more correct than using one partitioning tracer and one nonpartitioning tracer.
