Cost and Performance Report for LNAPL Recovery: Multi-Phase Extraction and Dual-Pump Recovery of LNAPL at the BP Former Amoco Refinery, Sugar Creek, MO
(EPA 542-R-05-016), 2005

This case study was prepared to summarize the recovery of light non-aqueous phase liquid (LNAPL) at two locations at the BP Products of North America, Inc. Former Amoco Refinery (former refinery) in Sugar Creek, Missouri. The purpose of this case study was to evaluate the cost and performance of two remediation systems - one innovative (high-vacuum multi-phase extraction) and one comprised of a more traditional approach (dual-pump LNAPL and groundwater recovery).

JV Task 109: Risk Assessment and Feasibility of Remedial Alternatives for Coal Seam at Garrison, North Dakota
J. Solc.
2007-EERC-12-07, 300 pp, 2007

The performance of SVE and multiphase extraction (MPE) for remediation of soil and ground water impacted by a hydrocarbon-contaminated coal seam was evaluated in Garrison, North Dakota, following the September 2005 release of an estimated 30,000 gallons of premium gasoline from an oil company facility. Free product was detected in cavities of the abandoned mine, as well as high concentrations of residual gasoline-based contaminants. SVE and MPE pilot tests confirmed high contaminant recovery efficiency at all three of the identified hot spots. The suggested remedial strategy is based on contaminant recovery and in situ degradation using a combination of thermally enhanced SVE in the source area, mobile MPE units transitioned to SVE in saturated impacted areas, and high-volume low-vacuum extraction from mining cavities based on a pioneering concept of controlled 'draft and channel' extraction technology.

JV Task 47: Demonstration of Vacuum-Enhanced Recovery and Feasibility of Permeable Treatment Barriers for Site Remediation at Hazen
J. Solc.
2006-EERC-09-09, NTIS: DE2007-908302, 62 pp, 2006

Summarizes a demonstration of multiphase extraction for vacuum-enhanced recovery of gasoline from soil and ground water at an Independent Oil site in Hazen, ND.

JV Task 59: Demonstration of Accelerated In Situ Contaminant Degradation by Vacuum-Enhanced Nutrient Distribution. Final Report
J. Solc.
2007-EERC-04-08, NTIS: DE2007-903316, 74 pp, 2007

Successful remediation of hydrocarbon-contaminated soils and ground water at a former Mohler Oil site in Bismarck, ND, involved the design, implementation, and operation of a mobile vacuum-enhanced recovery/multiphase extraction system combined with nutrient injection to reduce contaminant concentration levels in site soils and ground water.

Multi-Phase Extraction: State-of-the-Practice
EPA 542-R-99-004, 1999

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.

New Advancements for In Situ Treatment Using Electrical Resistance Heating

Remediation, Vol 17 No 2, p 51-70, 2007

At the Fort Lewis, Washington, East Gate Disposal Yard, chlorinated solvents (primarily TCE) and petroleum products are being treated in situ in several contaminant source areas using electrical resistance heating (ERH) and multiphase extraction. This paper updates the progress of the project and discusses data that provide insights into the biotic and abiotic degradation processes observed throughout the range of operating temperatures.
