Garrick Marcoux, P.G.

Mr. Marcoux has 10 years of experience in applied environmental/engineering geophysics. He acquired substantial relevant experience supervising geophysical projects for the largest geophysical consulting firm in the northeast where he established and managed a geophysical consulting office that serviced the greater New York metro area. He has conducted geophysical projects at municipal, state and federal government facilities (including U.S. Department of Defense (DOD) and Department of Energy (DOE) sites), as well as various industrial and commercial properties throughout the U.S. Mr. Marcoux has managed and conducted geophysical investigations using magnetic, spontaneous potential (SP), time- and frequency-domain electromagnetic (EM) induction, very low frequency (VLF) EM, ground penetrating radar (GPR), electrical resistivity, seismic refraction and borehole geophysical logging techniques. In addition, he is experienced with various land surveying instruments including global position systems (GPS) and total stations.

Mr. Marcoux's environmental experience includes substantial geophysical project experience on Superfund and FUSRAP (Formerly Utilized Sites Remedial Action Program) sites where radiological hazards are common. His engineering geophysics experience includes such diverse objectives as acquiring seismic data to aid in design of highway ramps and bridge piers, determining subsurface resistivities for electrical ground design for cell towers and power plants, and utilizing GPR to investigate the potential for soil loss beneath Federal Hall National Memorial. Archaeological projects Mr. Marcoux has been involved with include a geophysical survey of Liberty Island in New York Harbor that included the collection and interpretation of EM and Magnetic data as well as personally interpreting over 13 kilometers of GPR data collected at the site. Mr. Marcoux was also part of a similar project at the Bunker Hill Monument in Boston. His borehole geophysical logging experience includes the collection of high-resolution acoustic televiewer data along the proposed alignment of the Second Avenue Subway in Manhattan, collection of various logs including acoustic televiewer and EM flow-meter data for the DoE, and the conception and implementation of a video system to inspect caissons at 7 World Trade Center in support of reconstruction efforts at the site. Most recently, Mr. Marcoux has gained valuable experience action as the Site Inspection Technical Coordinator for FPM's Military Munitions Response Program contracts.

Mr. Marcoux received his B.S. in Geology from Western Washington University and his M.S. in Hydrology from the University of New Hampshire. He is a registered Geologist in New Hampshire and Tennessee, and he maintains annual OSHA Health and Safety Training. Mr. Marcoux is co-author of the following U.S. Geological Survey (USGS) documents: Lineament Maps of Areas 8-14 of the New Hampshire Bedrock Aquifer Assessment USGS Open File Reports (respectively): 98-191, 99-63, 9-64, 99-65, 99-89, 99-90, 99-91.
