Description:
The Pneumatic Fracturing Extraction(PFE) process developed by Accutech Remedial Systems, Inc. makes it possible to use vapor extraction to remove volatile organics at increased rates from a broader range of vadose zones. The low permeability of silts, clays, shales, etc. would otherwise make such formations unsuitable for cost-effective vapor extraction and require more costly approaches. Pneumatic fracturing provides an innovative means of increasing the permeability of a formation and thus extending the radius of influence so that contaminants can be effectively extracted.
