| "We hired Cooperstown Environmental LLC because we were impressed by their qualifications and their focus on solving our environmental challenges rather than monitoring them. They have done just that in a professional, competent, and cost-effective manner. Now we have retained them as experts to seek a rebate of some of our environmental costs. Now that's what I call value-added!” Phil Burton Senior Vice President GRAEBEL |

PROJECT: Cooperstown Environmental was retained by The Charles Stark Draper Laboratory to perform a site investigation at a research testing facility in Concord, Massachusetts in 2006 following the discovery of petroleum contamination during the installation of a new loading dock. This discovery came following an environmental investigation and remediation effort by others to address contamination associated with a release of hydraulic oil from research equipment. This previous effort had focused on contamination at the location of a former underground storage tank (UST), in historic dry wells and adjacent surface soils. Remedial efforts had been completed to the horizontal and vertical extent identified at that time. Cooperstown Environmental's work at the site was conducted pursuant to the Massachusetts Contingency Plan, and though historic efforts indicated a "clean closure", further investigation of the soil and groundwater in the vicinity of the loading dock installation indicated the presence of residual contamination. In 2006, a number of soil borings were advanced within the footprint of the former UST as part of a Release Abatement Measure (RAM) prepared by Cooperstown Environmental. The RAM focused on the horizontal and vertical delineation of petroleum impact. Soil samples were collected from borings and groundwater samples were also collected from monitoring wells installed at several of the borings. New release tracking numbers were assigned to the site based on the presence of elevated concentrations of Extractable Petroleum Hydrocarbons (EPH), Polyaromatic Hydrocarbons (PAHs), Lead and Arsenic in the soils and groundwater. In 2007, Cooperstown Environmental designed and installed a groundwater remedial treatment system to address contamination in the shallow groundwater table. The pump and treat system uses an oil water separator and a groundwater treatment system based on granular activated carbon (GAC) as a treatment medium. The groundwater treatment system is fed by two recovery wells located within and downgradient of the known releases. Additional investigations were conducted through 2010 after record drawings of the facility were recovered indicating that piping may have distributed oils and hazardous materials throughout the site. Continued efforts are ongoing to address source contamination beneath the footprint of this facility and plans are currently being considered for a horizontal drilling program to reach portions of the site that cannot be accessed using traditional drilling methods. Phase I and Phase II investigations have been completed and the Phase III feasibility studies are expected to be completed in the coming year.
