Previous investigators have demonstrated soil organic matter content as the major factor controlling organic substance adsorption in soil/water systems. In ground water (saturated) systems, it is expected that the least soluble constituents will remain within the soil matrix whereas the most soluble will leach and be carried along with the water flow. In cases where organic pollutants are bound to the solids matrix, it is important to determine whether pollutants will move through an aquifer with the soluble constituents or spatially remain localized with an insoluble constituent. The fate of a pollutant is thus dependent on which organic fraction it is adsorbed since not all fractions are active in sorption. This study focused on assessing the roles that the humic acid and humin contribute to adsorption in a particular system. Batch experiments using toluene as the sorbate and a material from the Cohansey aquifer outcrop (N.J.) identified humic acid as the prime adsorption factor.
