A method of analyzing soil vapor extraction (SVE) laboratory data using a sample of contaminated soil is presented to allow the calculation of equilibrium constants for an assumed gas/soil equilibrium expression. The constants can be determined for any compound measured in the exit gas. A Freundlich equilibrium expression was shown to represent the equilibrium in a soil contaminated with trichloroethylene (TCE) and several aromatic solvents.
