摘要

A treatability test to evaluate pneumatic fracturing was conducted at the Treatment Facility E (TFE) hotspot, one of over 20 source areas at the Lawrence Livermore National Laboratory Livermore Site, Livermore, California, that have been adversely impacted by chlorinated solvents. The primary objectives of the treatability test included: (1) evaluating changes in sustainable yield in ground water and soil vapor extraction through pre- and post-fracturing aquifer testing; (2) evaluating improvements in accessing contaminants isolated in tight source area sediments through quantifying changes in soil vapor and ground water extraction mass removal rates; (3) delineating propagated fracture patterns and sand proppant emplacement through detailed confirmation borehole core analysis, dye tracer analysis, and borehole videologging; (4) establishing remedial wellfield design parameters for future applications (fracture borehole spacing, extraction well completion techniques, etc.); and (5) evaluating potential adverse effects of the technology above and below the ground surface (soil vapor extraction short-circuiting through fracture “daylighting,” infrastructure damage, and inadvertent aquitard breaching).
