Predictive relationships that are presently employed for estimating the soil-water partitioning of nonionic organic pollutants do not account for the variable nature of soil organic matter. The capacity of selected components of soil organic matter to sorb trichloroethylene (TCE) and toluene, two nonionic volatile organic pollutants commonly encountered in contaminated groundwaters, is examined here. Sorption coefficients were determined and correlated with selected physico-chemical characteristics of the sorbents. Results indicate that the components of soil organic matter had widely varying affinities for toluene and TCE that cannot be solely explained by their organic carbon content. Multivariate regression results show that use of a sorbent's oxygen content as well as its carbon content yields a more accurate prediction of the sorptive partitioning coefficient than relationships that rely solely on the sorbent's carbon content.
