Description:
The U.S. Environmental Protection Agency (EPA), in cooperation with Accutech Remedial Systems (ARS) and the New Jersey Institute of Technology (NJIT) performed a field demonstration of Pneumatic Fracturing Extraction (PFE) for the removal of chlorinated volatile organics (VOCS) from vadose zones of low permeability. he demonstration was carried out during the fall of 1 992 at an industrial park in Somerville, New Jersey where removal of VOC contamination in shale bedrock was necessary to comply with New Jersey's Environmental Cleanup Responsibility Act (ECRA). uring the demonstration, air flow and contaminant concentrations were monitored to establish a database against which the developer's claims for the technology were evaluated. hese claims were that PFE would increase extracted air flow rates from the subsurface formation by at least 100% and would increase the mass removal rate for the key contaminant, trichloroethene (TCE), by at least 50%. n addition, although no claim was made, hot gas injection was also evaluated. ased on comparisons of 4-hour test results before and after fracturing, air flow rates increased more than 600 percent, and TCE mass removal rates increased about 675 percent.
