A mathematical mass transport model, the Vadose Zone Interactive Processes model, was employed to describe the fate of organic compounds codisposed in municipal refuse landfills. The model solves a convective-dispersive equation which incorporates transport and transformation processes of dispersion, advection, chemical and biological transformation, and sorption in unsaturated porous media. Using input data selected to describe laboratory refuse column operations and the operative physical/chemical phenomena, the predictive capabilities of the model were optimized. Test compounds included 12 organic compounds representing a broad range of organic classes. The mathematical model accurately predicted low mobility of hydrophobic compounds and described the migration of more hydrophilic test compounds in municipal refuse.
