Bioslurping is a new in situ technology that teams bioventing with vacuum-assisted free-phase fuel recovery to promote biodegradation in the vadose zone while simultaneously removing light nonaqueous phase liquid (LNAPL) from the water table and capillary fringe soil pores. Bioslurping differs from dual- or multi-phase extraction primarily in the same manner that bioventing differs from soil venting. The primary purpose of multi-phase extraction is to physically remove more volatile compounds from the groundwater, free product zones and vadose zone through use of high vacuum exerted usually below the water table. Bioslurping typically uses lower vacuum and removal of groundwater is minimized by placing a drop tube in the vacuum well near the free fuel-groundwater interface. Bioslurping is designed to accentuate in situ aerobic biodegradation and vapor extraction is an undesirable component. Thus this technology is ideal for the remediation of soils containing low volatility fuels.
