The Phase I assessment included reviewingavailable information on these World War II-era facilities, visiting sites, and developingsampling plans for investigations to be conducted in a subsequent phase.

Served as technical advisor for environmental investigations of various sites in Prince WilliamSound, Alaska. The project required evaluating possible site contamination resulting from oil-spill cleanup operations.

Served as project manager of a CERCLA RI/FS for a former solvents disposal facility inIllinois. Project activities included installing and monitoring private water supply carbontreatment units, installing groundwater monitoring wells and surface-water monitoring stations,conducting soil testing, monitoring groundwater and surface water, evaluating high-hazardmaterial incineration, providing risk assessment, and evaluating remedial action alternatives.

Managed installation of a recovery system in a railyard and downtown area in Mandan, NorthDakota. The system included four dual-pump recovery wells and related piping, control rooms,separator tanks, product storage tanks, meters, monitoring wells, and storm sewer and sanitar)sewer connections.
