Multi-Phase Extraction

  • Multi-Phase Extraction: State-of-the-Practice – 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).

  • Engineering Design – Multi-Phase Extraction – This Engineer Manual (EM) is intended to provide detailed guidance on all phases of remediation projects involving Multi-phase Extraction (MPE). This includes guidance on site characterization and pilot studies for MPE, considerations in screening MPE for a site; design of subsurface and above-ground components (excluding off gas and water treatment systems); and start-up, operations and maintenance, and site closure.
