Tasked to design and install a dual-phase extraction (DPE) groundwater treatment system under the oversight of the Mississippi Department of Environmental Quality (MDEQ) Underground Storage Tank Branch (UST), we have been able to reduce groundwater detection of BTEX from 12 groundwater wells to 5 groundwater wells during two years of operation. We recently recommended the installation of four additional recovery wells to optimize the system by increasing the vacuum influence on the portion of the site that has historically shown the highest concentrations of BTEX remaining in the dissolved plume.
