In situ isolation of volatile organic compounds from groundwater
Abstract
Methods and apparatus for in sire isolation of volatile organic compounds from groundwater using electrolytically-generated purge gas are disclosed. One preferred method includes electrolytically generating a purge gas from the ground water, passing the purge gas through the groundwater (in situ) to purge volatile organic compounds from groundwater, collecting the purge gas along with the purged volatile organic compounds, and detecting (in situ) the presence and/or amount of purged volatile organic compounds in the purge gas. One preferred apparatus includes a generally cylindrical cell incorporating the necessary electrodes, one or more ionization sources and detectors.
