Description	NAPL Simulator is a program for the simulation of the contamination of soils and aquifers which results from the release of organic liquids commonly referred to as Non-Aqueous Phase Liquids (NAPLS). The simulator is applicable to three interrelated zones: a vadose zone which is in contact with the atmosphere, a capillary zone, and a water-table aquifer zone. Three mobile phases are accommodated: water, NAPL, and gas. The numerical solution is based on a Hermite collocation finite element discretization. The simulator provides an accurate solution of a coupled set of non-linear partial differential equations that are generated by combining fundamental balance equations with constitutive thermodynamic relationships.
