Research is currently being conducted to enhance the existing pump-and-treat remediation strategy at the Petro Processors, Incorporated site (PPI)-a petrochemical disposal site consisting of two locations in East Baton Rouge Parish (Louisiana). Monochlorobenzene, a biodegradation byproduct of hexaclorobenzene, is a toxic chemical prevalent at the site; the diffusivity of monochlorobenzene is being studied through desorption experiments. The objective of soil desorption experiments is to determine soil-water distribution or partition coefficients. Partitioning is the distribution of solutes between two phases such as solid phase and a liquid (aqueous) phase. The derivation of acceptable partition coefficients "are used in [models] to determine the fate and transport of the contaminants at the site..." in an effort to further phytoremediation studies . Soil properties, such as bulk and particle density, are determined to describe the microenvironments of the contaminant. These properties relate the number of pores with the mean length a molecule of contaminant must migrate to reach the outer surface of a soil particle. The partition coefficient, the bulk density tell are MCB flux parameters. Flux describes the amount a contaminate migrates, in a given time, over the area in which the contaminant is exposed.
