RESULTS

TPH Concentrations Before SVE

TPH Conc. After SVE: 2 Layers, Contrast = 10,000

TPH Conc. After SVE: 16 Layers, Contrast = 20

TPH Conc. After SVE: 16 Layers, Contrast = 10,000

TPH Conc. Through Time: Geologic Case #1, Intrinsic Perm. Contrast = 20

TPH Conc. Through Time: Geologic Case #2, Intrinsic Perm. Contrast = 100

TPH Conc. Through Time: Geologic Case #3, Intrinsic Perm. Contrast = 10,000

Initial vs. Final TPH Conc. for each Perm. Contrast & Bed Thickness
