Dual-phase / multi-phase extraction (DPE/MPE) is a general term for technologies that extract volatile organic chemicals (VOCs) in soil vapor and groundwater simultaneously. Multi-phase extraction systems utilize a vacuum system, which can also be combined with a down-hole pumping system, to remove various combinations of contaminated groundwater, non-aqueous phase liquids (NAPLs), and their associated vapors from the subsurface. By lowering the water table around the contaminants, DPE/MPE systems expose and influence more of the contaminated media/formation, thereby allowing the newly exposed vadose zone to be treated by vapor extraction. Once pumped to the surface, the associated liquids and organic vapors are separated and treated.
Dual-phase / multi-phase extraction systems target sites with light non-aqueous phase liquids (LNAPLs), dense non-aqueous phase liquids (DNAPLs), and/or high concentrations of their dissolved constituents. This remediation approach is faster, safer, less invasive, and more economical than more traditional remediation approaches.
RECON has the experience, team, and resources to implement the following mobile DPE/MPE centered technologies at sites throughout North America.
