representative projects
  • Principal-in-Charge of the Remedial Investigation/Feasibility Study for the Shore Realty Superfund Site in Glenwood Landing, New York. Evaluated the extent of volatile organic chemicals, metals and PCBs in soil, sediments, and groundwater. Demonstrated the technical impracticability of groundwater remediation to meet New York State Cleanup levels. Evaluated and pilot tested in situ cleanup methods, including soil vapor extraction, and negotiated a cost effective remedy with the NYSDEC and USEPA.
  • Principal-in-Charge of the Remedial Investigation/Feasibility Study for the Delaware City PVC Plant Superfund Site in Delaware City, Delaware. Conducted an extensive groundwater investigation, including installation of numerous monitoring wells, an aquifer pumping test, and a geophysical evaluation of a confining clay layer. Evaluated various remedial options and determined that pump and treat would be an effective method at this site because of the nature of the impacted aquifer and the specific chemicals of concern. Designed a groundwater capture system that has effectively halted the migration of the plume and has cleaned up major portions of the aquifer to non-detect levels.
  • Project Manager for the Remedial Investigation of the Industri-Plex 128 Superfund Site in Woburn, Massachusetts (ranked No. 5 on the National Priorities List). Conducted an extensive investigation of soil, sediment, surface water, and groundwater contamination. Contaminants of concern included arsenic, lead, chromium, and volatile organics. Made extensive use of geophysical techniques to map the extent of buried wastes. Evaluated groundwater flow patterns and groundwater/surface water interactions and the use of engineered wetlands as a groundwater remedial measure. Negotiated investigative and remedial activities with USEPA Region I. Made regular presentations to the local Citizens Advisory Committee.
