In situ soil mixing coupled with hot air/steam injection is a means for overcoming low-permeability conditions and treating soils contaminated with volatile and semivolatile organic chemicals (VOCs and SVOCs). A process model was developed to simulate heat and mass transport during combined in situ mixing and thermal treatment of unsaturated soils contaminated with low levels of VOCs. The soil treatment zone was assumed to consist of a series of equal-volume, continuously-mixed compartments. Thermal and chemical equilibrium were assumed to exist among the solid, water, and gas phases in each compartment. A literature correlation was incorporated into the model to account for the temperature dependence of Henry's constant.
