||The report summarizes and analyzes the SITE demonstration of Accutech's Pneumatic Fracturing Extraction (PFE) process at an industrial park in NJ. Based on the results of 4-hr tests before and after fracturing, extracted air flow rate increased an average 600% and trichloroethene (TCE) mass removal rate increased about 675%, primarily due to the increased air flow. The radius for effective vapor extraction also is enlarged by fracturing; extracted air flow rates increased 700% to 1,400% in wells at a 10 ft radius and 200% to 1,100% in wells 20 ft from the fracture well. With passive air inlets, the extracted air flow rate increased about 19,500%, and TCE mass removal rate increased 2,300%. The estimated cost for full-scale remediation of the site with PFE was $307/kg ($140/lb) of TCE removed based on the SITE demonstration experience and information provided by the developer. Major contributing factors were: Labor (29%); Capital Equipment (22); and Emissions Collection/disposal (19%). Numerous assumptions were used in arriving at this cost. Results of two Hot Gas Injection (HGI) tests were inconclusive.
