In situ remediation by 2-PHASE{trademark} -- A 2-year success story
As part of Xerox Corporation`s worldwide commitment to assess and remediate the environment of their facilities, 2-PHASE{trademark} Extraction was used to remove subsurface volatile organic constituents (VOCs) at one their manufacturing plants in Ontario. The 2-PHASE Extraction system, developed by Xerox as an alternative to conventional pump-and-treat technology, uses a high-vacuum source applied to an extraction tube within a recovery well to increase groundwater removal rates in low-permeability geologic settings. 2-PHASE Extraction removes both subsurface liquids and vapors, thus improving contaminant removal rates, and simplifies post-extraction groundwater treatment because as much as95% of the VOCs in the water phase are transferred to the vapor phase. Site investigations at the Ontario facility indicated that chemical releases from underground storage tanks and solvent spray booths had resulted in two distinct areas of localized soil and groundwater contamination. Contamination occurred inside the plant building under the floor slab of a manufacturing area at the location of a former solvent spray booth and underground storage tanks. Contamination also occurred outside the building at the location of two former underground 7,000 gallon solvent storage tanks. Contaminants present were primarily 1,1,1-trichloroethane (1,1,1-TCA), tetrachloroethene (PCE), trichloroethene (TCE), and their associated degradation products (trans-1,2-dichlorethene, 1,1-dichloroethene and 1,1-dichloroethane). Mineral spirits were also present.
