Abstract Environmental contamination problems commonly involve Wastes consisting of complex mixtures of chemicals. The behavior of these mixtures has not been well understood because the primary chemodynamic properties (e.g. Solubility, sorption, transport) of organic chemicals have usually been characterized in aqueous solutions which are simple in composition relative to many waste mixtures found at or near disposal/spill sites. Typically, laboratory studies have focused on chemodynamlcs of single solutes in water or In dilute electrolyte solutions. The research summarized in this report focuses on the effects which organic cosolvents have on the sorption and mobility of organic contaminants. This work was initiated in an effort to improve our understanding of the environmental consequences associated with complex mixtures and to enhance our ability to deal with these consequences in a technically responsible manner. Specific objectives of the project were to: (1) Measure solubility and sorption for selected organic chemicals in complex solvent mixtures consisting of mixtures of organic cosolvents and water; and (2) Utilize isocratic- and gradient-elution techniques to characterize the Impacts of organic cosolvents on the transport of hydrophobic organic chemicals in soils and aquifer media. The results of this work have application to the definition, prediction and remediation of soil and groundwater contamination problems. Since an increase in the concentration of organic cosolvents.
