Abstract
A numerical simulator has been developed to model the spatial and temporal variation of multicomponent NAPL composition and dissolved phase concentrations in a groundwater environment. The model accounts for NAPL solidification that may result as constituent compounds reach their solubility limits in the organic liquid. Simulations were run for NAPL mixtures of polycyclic aromatic hydrocarbons (PAHs). Thirty-year simulations demonstrate that the NAPL slowly becomes depleted of the lower molecular weight compounds. The enrichment of the NAPL with respect to the more carcinogenic compounds implies limited reduction in human health risk, despite the continued reduction in overall NAPL volume.
