This report describes the state-of-the-practice for multi-phase extraction (MPE) of contaminated soil and groundwater, focusing primarily on the application and use of MPE at sites with halogenated volatile organic compounds (VOCs). MPE is an innovative technology that has the potential to be more cost-effective and to remediate sites more quickly than with use of conventional technologies.
