The transport of 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) in soils containing various organic liquids has been measured experimentally. A model has been developed that considers diffusive transport in the liquid phase and takes into account the rate of adsorption and desorption of TCDD from the soil particles. Effective diffusion coefficients for TCDD were fit to the data, and the results compared well with estimates using the Wilke-Chang correlation.
