Project Example
The State of Vermont required remediation of perchloroethene-contaminated soil and groundwater at a former dry cleaning facility in Bennington. The site today lies within a large, busy parking lot accommodating vehicles from several national retail chains.
New England EnviroStrategies worked with four different potentially responsible parties, State regulatory officials, representatives of the Town of Bennington and the national chains to develop a remedial approach that maximized source control and management of migration while minimizing site disruption and cost.
Following a detailed data review and compilation of existing data into GIS, New England EnviroStrategies used that information to produce a groundwater flow and transport model showing that insitu chemical oxidation could reduce PCE concentrations to meet regulatory goals. A sodium permanganate oxidation remedy was subsequently chosen by the State and implemented at the site by New England EnviroStrategies. The site is currently in monitoring mode and is projected to save approximately 40% in cleanup costs relative to more invasive and disruptive technologies, while still meeting project objectives.
