In the paper, the authors present sorption data for selected organic solvents on several subsurface materials. The goals of the study were to advance the qualitative understanding of sorption of four widely-used organic solvents from aqueous solution onto natural sorbents with low f(sub oc) and to attempt to more quantitatively define a mineral component to that sorption. The ultimate objective was to facilitate a sound basis for predicting transport behavior of dissolved solvents in aquifers. The work first focused on characterizing PCE sorption on samples obtained primarily from two semi-continuous subsurface cores, and then on sorption of four nonpolar organic solvents on three saturated zone sorbents with low organic carbon content.
