This paper presents the results from a well-defined, circular-shaped, multicomponent dense nonaqueous phase liquid (DNAPL) pool dissolutionexperiment conducted in a three-dimensional, bench scale model aquifer. The multicomponent pool is a mixture of tetrachloroethylene(PCE) and 1,1,2-trichloroethane (1,1,2-TCA); PCE was the major component and 1,1,2-TCA was the minor component. Downgradient plumeconcentrations were measured at five specific locations over time until the majority of the 1,1,2-TCA was depleted from the DNAPL poolsource. The experimental results suggest distinct spatial-temporal plume patterns for minor DNAPL components versus major DNAPL components.The downgradient concentration varied over time for 1,1,2-TCA while a stable plume developed for PCE. A semi-analytical solutionfor contaminant transport resulting from dissolution of multicomponent nonaqueous phase liquid pools successfully simulated the plumestructure and dynamics for both the major and minor DNAPL components.© 2005 Elsevier B.V.
