Objective:

The release of light nonaqueous phase liquids (LNAPLs) into the subsurface is a well-documented environmental concern.  Past practices have led to extensive LNAPL groundwater contamination, mostly in the form of petroleum products.  Potential for further contamination also is a concern when considering the presence of LNAPL sources in the subsurface (e.g., underground storage tanks and oil/gas pipelines).  Surfactant enhanced aquifer remediation has emerged as one of the most technically effective and cost-competitive technologies for remediation of LNAPL contamination.  This technology has applications to filling stations, refineries, and even active well sites.  Although advances in surfactant chemistry dramatically have improved LNAPL removal efficiencies, the key to further improvements in the economic competitiveness of surfactant-based technologies is to reduce the mass of surfactant needed to recover the free-phase LNAPLs.  Previous work by the investigators found that some biologically produced surface active agents, biosurfactants, can remove a large percentage of residual hydrocarbon from sand-packed columns at biosurfactant concentrations 10- to 100-fold lower than typically used for surfactant-enhanced LNAPL mobilization.  The objective of this research project was to assess the relative technical and economic efficiency of synthetic surfactants versus biosurfactants for recovery of LNAPL contamination.
