SVE is specilarly effective for petroleum hydrocarbons, chlorinated solvents like trichloroetylene (TCE), and tell comm chemicals. The technology works best in permeable, porus soils such as sands andd gravels, where water flow is unimpeded. However, in finer-grained soils or heterogeneous formations, performance can drop off.
