Auburn Road Landfill Superfund Site PRPs; Londonderry, NH    

Conducted a pilot treatability study to assess the effectiveness of activated alumina adsorption and various oxidation, coagulation, and precipitation combinations for treating arsenic and iron in groundwater.  Pre-design report summarized the unit operation for implementation, sludge yield, and capital and O&M estimates.  


Lockheed Electronics Co.; Plainfield, NJ    

This treatability study assessed the effectiveness of Closed Cell Soil Aeration and Soil Vapor Extraction for treating TCE and PCE in the sandy fills and the native clay soils at the Lockheed Electronics Co. site in Plainfield, NJ.  This study also evaluated the effectiveness of off-gas capture and treatment.  


McKin Superfund Site PRPs; Gray, ME    

In situ permeability testing included a constant rate groundwater pump testing program to determine full-scale extraction rates at the McKin Superfund site.  The groundwater extracted was contained and used for conducting a pilot treatability study.  During the study, the suitability of air stripping and aqueous phase GAC adsorption for treating volatile organics in the groundwater was determined.  In addition, the need for pretreatment of the groundwater was assessed and the effectiveness of vapor phase GAC adsorption to control air emissions from a packed tower air stripper was evaluated.  


McKin Superfund Site PRPs; Gray, ME    

Designed groundwater extraction and treatment system consisting of four extraction wells, over a mile of pressure force main, centralized treatment system, and on-site infiltration gallery.  Treatment system included a packed tower air stripper, aqueous GAC polishing, vapor phase GAC adsorption, treatment plant building, instrumentation and controls.  Construction management included normal construction oversight, as well as extensive interaction with neighbors to this Superfund site.  Provided operational support during the 10 years of operation before the system was retired as a result of achieving the groundwater remedial action standards. 


Humboldt and Rumford National Graphics; Belfast, ME    

A petroleum (No. 2 fuel oil) and solvent (TCE and PCE) spill occurred at the former Rumford National Graphics site.  The feasibility study recommended a series of bedrock recovery wells and a treatment system consisting of an oil/water separator, oil product recovery system, a shallow tray aerator, force mains, a gravity sewer outfall, and an on-site reinjection chamber.  The treatment facility was integrated into the on-site warehouse.  Responsible for the system start-up and operations support.  


Former Electro-Signal Lab Trust; Rockland, MA    

Completed a feasibility study and remedial design for a groundwater extraction and treatment system (GETS) to remediate a solvent plume at the former ESL site.  Remedial design included a series of extraction wells, a treatment building to house a shallow tray aeration and vapor plume GAC adsorber, instrumentation and controls, and a gravity outfall.  Provided system start-up and long-term operations support.  


Former Benda Products Trust; Canton, MA    

A tanker spilled about 200 gallons of PCE at the former Benda Products site.  The remedial design included a series of vapor extraction wells, two groundwater recovery wells, a shallow tray aerator for treating the groundwater, and a combined vapor phase treatment process for treating both the off-gas from the aerator and the vapor extraction wells.  Due to the high concentration and mass of PCE to be treated in the vapor system (PCE at saturation in the groundwater), a thermal desorption system was installed for vapor phase treatment. 


Maine Metal Finishing (former Silvex site) and Maine Department of Environmental Protection; Gorham, ME    

This facility’s finishing and plating process discharged wastewater to on-site lagoons that resulted in residual solids and contaminated soils and groundwater.  Contaminants included chromium, cadmium, nickel, cyanide, and various chlorinated solvents.  The plume discharged via seeps on the floodplain boundary of the Stroudwater River.  Remedial design recommendations included containment of the seeps, groundwater extraction, aqueous metals precipitation, and GAC adsorption for solvent removal.  Design was not implemented due to the demonstation by the project team to the regulators that migration of contaminated groundwater is under control. 


Auburn Road PRP Committee; Londonderry, NH    

The Auburn Road Landfill site comprised 200 acres of land and four discrete disposal areas that were found to be the source of VOCs and arsenic that were flowing off-site and contaminating the groundwater.  Source controls included constructing multi-layered caps over each of the four areas.  The original management of migration action included groundwater extraction and treatment.  As part of the program, the argument was made that VOC contaminant levels at the site boundary had declined to below acceptable levels and that the arsenic present was naturally occurring and not of an anthropogenic source.  U.S.EPA agreed and amended the determination for a need to install groundwater treatment.  Instead, institutional controls were recommended, including continued monitoring to document natural attenuation.


American Annuity Group Relating to the former Sprague Electric Company Site; Sanford, ME    

Two industrial lagoons, a former drywell, and a leaking petroleum underground storage tank resulted in contaminating the groundwater with chlorinated organics and aromatic hydrocarbons.  The feasibility study and preliminary remedial design identified that a migration control option would be very expensive and provide marginal benefit.  In addition, numerous attempts were unsuccessful to identify additional source areas.  As a result, the argument was made that there are no pathways for human exposure and that institutional controls in the form of environmental covenants are acceptable for mitigating risk at this site.  MEDEP agreed with the determination and no active management of migration was necessary for this site. 


W.H. Shurtleff Co.; South Portland, ME    

The remedial design included three extraction wells, force mains, a shallow tray aeration process, vapor phase GAC adsorption, instrumentation and controls, and discharge to the South Portland wastewater treatment plant.  The treatment plant was integrated into an active manufacturing area of the site.  Responsible for system start-up and operational support. 


U.S.EPA REM/FIT Contractor; Region 7    

Participated in completing the Remedial Investigation/Feasibility Study (RI/FS) for former horse farms as well as Times Beach, MO, where oils mixed with still bottoms contaminated with dioxins were sprayed on roads and horse tracks for dust control.  Extensive analyses of source control options were completed, including biological, physical/chemical, and thermal technologies for treating the dioxin-contaminated soil.
