The technology is an enhancement process designed for integration with primary in-situ treatment technologies such as vapor extraction, bioremediation, thermal treatment, and 'pump and treat'. Fractures in dense soils are created, using hydraulic or pneumatic methods, making existing fractures larger to get at contaminants and allowing a more effective distribution of the extractive air throughout the soil. Pneumatic Fracturing was jointly developed by Accutech Remedial Systems Inc. and the New Jersey Institute of Technology. It involves the injection of air (or another gas) into a contaminated geologic formation at sufficient pressure and flow rate to create artificial fractures or to extend natural fractures.
