This research developed a series of probability plots identifying the efficiencies of soil vapor extraction (SVE) as a function of soil type, spill size, and vacuum applied. the technique employed involved modifying an agronomic soil moisture model to further simulate air permeabilities for the various soils investigated. Probability density functions were developed for these permeabilities as well as for the expected BETX and Total Hydrocarbon recoveries. Comparisons to other approaches showed the method to be valid while providing a full range of probabilities for each of the metrics of concern.
