2 The ex-situ Technology is also fully sustainable,relying onvapors generated through thermal treatmentof soils to serve as fuel for operation of the system; thissignificantly reduces operational costs relative tootherthermal treatment in-situ component of the VEG Technology relies onthe highly efficient vapor generator to change the physical propertiesofsoilcontaminants, NAPLs,crude oil, andfuelsin the subsurface, allowing for subsequent Full treatment of gasoline, diesel, jet fuel, motor oil, and manufacturedgas plant (MGP) wastes in soils Treatment of VOCs ( , benzene, TCE, PCE, vinyl chloride), SVOC sand PAHs, PCBs,pesticides, and PFCsin soils for unrestricted ( ,residential)
