Description:
Two pilot-scale demonstrations of the hydraulic fracturing technology for enhancing the permeability of contaminated silty clays have been evaluated under the Superfund Innovative Technology Evaluation (SITE) Program.The hydraulic fracturing technology was demonstrated in 1991 and 1992 at a extraction site in Oak Brook, Illinois, and at a bioremediation site near Dayton, Ohio. he technology was jointly developed by the University of Cincinnati (UC) and the Risk Reduction Engineering Laboratory. ests were also conducted at UC Center Hill Solid and Hazardous Waste Research (Center Hill) Facility by UC. hese tests were conducted to determine the factors affecting soil vapor flow through sand-filled hydraulic fractures.At the OakBrook Site, these fractures increased vapor flow by one order of magnitude in an area 30 times greater than the area affected by wells in unfractured soil. t the Dayton Site, the groundwater flow rate was 25 to 40 times higher in a well screened in the fractured soil than in one screened in unfractured soil.
