Abstract: In recent years, much attention has been focused on the migration of the soluble portion of an organic contaminant in groundwater systems. Little work, however, has been directed towards the modeling of the movement of the non-aqueous phase component of a spill. A two dimensional mathematical model is presented which is capable of describing the movement of an organic as both a non-aqueous liquid and as a component of the water and gas phases. Governing equations are discretized using a finite difference scheme and the resulting system of algebraic equations is solved by a Newton-Raphson procedure. In order to apply this model, a detailed knowledge of matrix and fluid properties such as relative permeabilities, capillary-pressure relations, densities, and dispersivities is required.
