Dual Phase Extraction (DPE) uses a newly approved remedial alternative to remediate both soil and groundwater at various sites within the region.  DPE, also known as multi-phase extraction or vacuum-enhanced extraction is a technology that uses a high vacuum system to remove various combinations of contaminated ground water, petroleum product, and hydrocarbon vapor from below ground.  Use of DPE technology can often reduce the cleanup time at a contaminated site and, consequently, result in realized cost savings.
