Dr. Florin Gheorghiu

M.Sc., Engineering Geology/Geophysics, University of Bucharest, Romania, 1977
Ph.D., Water Resources, University of Waterloo (in progress) ?

Dr. Gheorghiu is an Associate of Golder Associats Inc, with extensive experience in theoertical and practical aspects of fractured rock hydrogeology for environmental projects. Dr. Gheorghiu is responsible for management and coordination of geological, hydrogeological, and geophysical investigations for environmental and civil engineering projects including contaminant investigations, and municipal landfill design projects.

Dr. Gheorghiu's major activities over the past 20 years have included groundwater flow and solute transport modeling using computer codes FLOWPATH, MODFLOW, MODPATH and FTWORK, for contaminant plume characterization, civil engineering projects and remedial system design including extraction/reinjection system design, cut-off wall design and hydraulic containment of NAPL contaminated sites; Probabilistic assessment of monitoring system efficiency; Probabilistic assessment and Monte Carlo simulations of groundwater flow and contaminant migration rates; Designing, conducting and analyzing various aquifer tests in porous and fractured media such as: step-drawdown tests, constant rate pumping tests, withdrawal/injection or pulse tests using straddle packer assembly, constant rate or constant head pump-in tests, etc.; Defining nature and extent of contaminant plumes, including DNAPL and LNAPL plumes, using geologic, hydrogeologic, geochemical, and geophysical data at industrial and landfill sites; Integration of regional and site geology/hydrogeology based on drilling, trenching, geologic mapping and aerial photographs; Writing expert witness reports; Geotechnical and hydrogeologic assessments for potential landfill sites including baseline hydrogeologic conditions for Phase I and Phase II permit application.

Representative projects and clients included: Modern Landfill, WMNA, PA; Elizabethtown Landfill, WMNA, PA; Pottstown Landfill, WMNA, PA; Harmony Grove Landfill, WMNA, PA; Cinnaminson Landfill, WMNA, NJ; Monroe Landfill, BFI, NJ; Tabernacle Drum Dump Site, USX NJ; Sandy Hill Landfill, WMNA/Prince George's County, ME; Wheatfield Plant, Bell Aerospace Textron, NY; Lyman Street and East Street Sites, General Electric, MA; Woburn, ISRT, MA; Coakley Landfill Superfund Site, Coakley Landfill Group, NH; Duffield Plant, Cyprus Foote Minerals, VA.

• Continuum modeling for fractured rock masses
• Environmental assessment and remediation of DNAPL and NAPL contaminated rock
• Design of site monitoring
• Bioremediation
• Packer testing
• Probabilistic methods
