Vapor Intrusion Study
Large Multi-Tenant Department
of Defense Facility

Technical lead for a vapor intrusion screening evaluation of 16 site areas with VOCs in groundwater, 2 of which also have soil impacts. The study relied primarily on existing information to identify areas of groundwater contamination with an overlying “clean water lens.” Remaining areas were then evaluated with respect to proximity of contaminants to buildings and preferential airflow pathways, depth to groundwater, contaminant concentrations, and concentration trends over time.

Assessment of Pitch Lagoon in Bahrain
Oil Company

Designed, supervised, and evaluated laboratory studies of pitch and sediments at a 126‑acre refinery lagoon. Analyzed pitch for physical characteristics, heating value, and composition. Evaluated impacts of the lagoon on surrounding groundwater and assessed potential biodegradability of pitch‑affected soils. Evaluated options for dealing with the pitch and its impacts.

Radiological Assessment of Former Combustion Engineering Site in Windsor, Connecticut
U.S. Army Corps of Engineers

Served as technical lead on an investigation of a former U.S. Department of Energy site with radiological contamination (uranium, cobalt, and nickel radionuclides). The study involved on-site and/or off-site laboratory analysis of over 1,000 samples of soil, groundwater, sediment, surface water, and building materials.

Comprehensive Site Assessment and  Feasibility Study
Food Manufacturer

Evaluated a complex tidally influenced Massachusetts site near human and environmental receptors. Work included evaluation of the interaction of groundwater and surface water, risk assessment, contaminant fate and transport modeling, and advanced fingerprinting analysis of site product and adjacent surface water sheen samples. Evaluated the feasibility of remedial alternatives to be applied in conjunction with a proposed site development.

Reserve Pit Groundwater Monitoring
Oil Company

Reviewed salts, metals, and petroleum hydrocarbons data from seven years of monitoring and provided recommendations for future water quality monitoring outside drilling pad reserve pits on Alaska’s North Slope.
