Print this pageRemediation of soil and groundwater contaminated with chlorinated solvents at a former underground storage tank site is attempted using BIOx, a jettable slurry of calcium hydroxide and hydrogen peroxide. A 5-10% BIOx slurry is jetted into the subsurface using a high-pressure wand which advances its boring by liquefication of the soil in front of it. The speed and ease of jetting allowed borings to be placed approximately 1.5 feet apart, to a depth of approximately 15 feet. Comparison of groundwater sample results collected before and 4 weeks after treatment indicate that regulated dissolved chlorinated compound concentrations have declined approximately 50%. The mechanism of affect is expected to continue to reduce concentrations for several weeks.
