Enhanced In Situ Bioremediation of Groundwater Impacted by Chlorinated Solvents at Intensol, LLC Site

Groundwater below this four-acre former manufacturing facility was contaminated primarily with PCE and TCE, presumably from historic releases at the site, resulting in the shutdown of three municipal supply wells. One of these supply wells, located approximately 3,000 feet from the site, had been retrofitted with an air stripper in the mid-1990s to limit migration of the groundwater plume. The State accepted a pump and treat remedy to address the source area below the former plant after previous contractors had attempted air sparging and chemical oxidation without success. Intesol's goal was to accelerate the time to closure relative to the pump and treat remedy by identifying alternatives for source area remediation; determining if those alternatives could be implemented quickly; preventing natural groundwater flow from carrying source area contaminants towards the downgradient supply wells; and remediating site contaminants.

Nuclear Metals, Inc. Superfund Site Remedial Investigation and Feasibility Study

Nuclear Metals, Inc. (NMI) used depleted uranium (DU) in the manufacture of penetrators for the US Army. From 1958 to 1985, process waste (DU, nitric acid, and lime) was disposed in an unlined holding basin at this Boston-area manufacturing facility now surrounded by residential neighborhoods. As a result, DU was released to soils and groundwater near the basin.

Implementation of an In Situ Thermal Desorption Remedy for Regulatory Site Closure

A portion of the privately owned "Route 44" property was excavated in the 1930s for fill for an off-site construction project. The resulting borrow pit was gradually filled with drums containing a variety of wastes. In the 1990s, the U.S. EPA conducted a series of site characterization studies, and in 2001, removed over 800 drums from the site. These removal activities were suspended after labels bearing the name of a nearby manufacturer were found on some of the drums. EPA then sent a Remedial Action letter to the corporate successor of that firm, who subsequently retained Geosyntec to provide oversight of the remaining drum removal activities, as well as to guide the site through the subsequent site assessment and remediation process and to ultimately achieve regulatory closure under the Massachusetts Contingency Plan (MCP).

Comprehensive Remediation and Design/Build Services at a Buried Drum Site

The 6-acre St. Germain Site in Taunton, Massachusetts had formerly been used as a heavy equipment staging and storage area. The former site owner operated a waste hauling business and had buried drums and impacted soils on the property from multiple offsite sources. In 1999, U.S. EPA initiated a Time Critical Removal Action at the site and subsequently excavated over 700 drums from the subsurface. In May 2000, the property owner and a nearby manufacturer were issued an Administrative Order on Consent (AOC) by the U.S. EPA and later a Notice of Responsibility (NOR) by the MassDEP. The corporate successor of that firm retained Geosyntec to perform an initial site investigation at the site in 2000. Geosyntec provided oversight for the AOC and NOR mandated excavation of 4,000 buried drums and 12,000 cubic yards of soil. During these activities, a complex mix of contaminants was identified, including petroleum hydrocarbons, chlorinated ethenes and benzenes, a number of other volatile and semi-volatile organic compounds, and proprietary chemicals.

Design and Construction of a Slurry Wall and Engineered Cap for Site Redevelopment

A portion of the privately owned former industrial manufacturing site known as the "Route 44" property was impaired by the presence of contaminants from past site uses. Geosyntec was selected to develop an engineered solution for the containment and isolation of residual contaminants and to render the property suitable for redevelopment as a Brownfields site.
