“…Furthermore, a non-linear relationship of C i,eq and c i indicates that molecular interactions of a solute in the organic liquid solution are different to the interactions of the compound in its pure liquid phase, and g i therefore, deviates from unity depending on concentration. A general form of Raoult's law including the relationship of g i and c i could be used to express the dependency of the g i on the system composition as used by others in experiments (Ghoshal et al, 1996) and simulation studies (Lee et al, 1998;Lee and Chrysikopoulos, 2006). In this case, S i,sub can also be calculated by a non-linear extrapolation to the point where c i becomes one if the function could be defined explicitly or implicitly.…”

“…PCE and TCE are used as degreasers, dry cleaning fluids and solvents in many industrial and commercial processes, and are often released to the subsurface [2]. The physical and chemical properties of DNAPLs, aside from their relatively low solubility [3], high specific gravity [4] and tendency to remain adsorbed to organic and fine-grained materials [5], make DNAPLs difficult to locate and characterize in the subsurface [6], and this can impact the effectiveness of conventional remedial technologies [7]. Upon their release at the ground surface, DNAPLs tend to migrate downwards through the saturated zone [8], and over time they accumulate in layers with lower permeability [3,9], from which they are then difficult to mobilize with traditional pumping systems [10].…”

“…Chlorinated solvents, including trichloroethylene (TCE) and tetrachloroethylene (PCE), are the most important subclass of DNAPLs [2] due to their widespread use in the electronics, chemical, dry cleaning, and metal fabrication industries [3]. The physical and chemical properties of DNAPLs, aside from their relatively low solubility [4], high specific gravity [5], and tendency to remain adsorbed to organic and fine-grained materials [6], make them difficult to locate and characterize in the subsurface [7], and this can impact the effectiveness of conventional remedial technologies [8].…”
