Abstract

Removal of Light, non-Aqueous Phase Liquids (LNAPLs) from contaminated soils is expedited by injecting gas into extraction wells. The extraction wells are operated with a vacuum assist which produces a mounding of groundwater around the well. Gas is injected into the groundwater within the extraction well in the form of micro-bubbles. The bubbles rise through the LNAPL and volatilize it. The volatilized LNAPL is drawn to the surface and groundwater is left in the well.
