The risk assessments and remediation of the sites, potentially contaminated with LNAPLs, are constrained by their incomplete characterization. The usual method of partitioning tracer test neglects the effect of sorption to the soil organic matter. The purpose of this paper is to demonstrate the effect of sorption of tracers to the soil organic matter on the quantification of LNAPLs (Light None Aqueous Phase Liquids) from experimental results. Diesel is used as NAPLs in this laboratory scale column investigation. Method of moment is used for estimating the saturation of LNAPLs in the columns. The experimental results are from sorption isotherm tests with selected soils and partitioning tracer experiment with columns packed with selected soils and their mixtures. However, there were no contaminants added, breakthrough curves from Columns, packed with mixture of Jumonjin sand and organic matter, showed separation of tracers. Columns were then contaminated to residual saturation with diesel and breakthrough curves were obtained and the results were compared which shows that sorption of tracers to soil organic matter lead to an overestimation of the quantification of NAPLs. The amount of organic matter in the soil was determined by incineration. The sorption of tracers proportionally increased with the increase of the organic matter contents of the soil.
