Multicomponent NAPL pool dissolution in saturated porous media C.V. Chrysikopoulos, K.Y. Lee Department of Civil Engineering, University of California, Irvine C4P2777, C/SW ABSTRACT In this paper, we study the multicomponent transport of contaminants originating from the dissolution of NAPL pools in saturated porous media. A semi-analytical proce- dure is introduced. The method assumes that the contaminant source input can be represented by a series of short pulses. For the duration of each pulse the equilibrium aqueous solubility of every pool constituent is considered invariant. The mole fraction, nonaqucous phase activity coefficient, and consequently, the aqueous solubility of every pool constituent are updated before each pulse period. The procedure is illustrated for a hypothetical site contaminated by three NAPL pools consisting of 1,1,2-trichloroethane (TCA) and trichloroethylene (TCE) mixtures. INTRODUCTION There are several studies available in the literature focusin
