About Us

Pyramid Geophysical Services offers a full line of geophysical capabilities to North Carolina and across the United States. We have experience in a wide variety of geographical areas and projects, including hazardous waste sites, underground storage tanks, landfills, groundwater studies, and geotechnical investigations. We design geophysical surveys that meet the client’s needs in the most efficient and cost effective manner possible.

Our typical approach incorporates a multi-phase geophysical reconnaissance technique specifically designed to provide the most accurate site information possible while taking into account both the capabilities and limitations of the various geophysical methods we offer.

Pyramid prides itself on quality surveys. We make every effort to assure integrity of field data, including frequent quality assurance analyses during acquisition.

Key Personnel

Senior Geophysicist

Eric Cross, P.G.

Eric Cross geophysicistAll work is closely supervised by Eric Cross, P.G, our Senior Geophysicist.  Mr. Cross obtained his Bachelor’s degree in Earth and Ocean Sciences from Duke University, and a Master’s degree in geochemistry and marine science from the University of South Florida. He is a licensed geologist in the states of North Carolina, South Carolina, Tennessee, and Florida, with experience in a wide variety of fields including near surface geophysical methods, geologic mapping, geotechnical investigations, and environmental assessments. At Pyramid, Mr. Cross employs a variety of geophysical instruments including electrical resistivity, ground penetrating radar, seismic methods, and electromagnetic surveying tools.

His experience with near surface geophysics includes projects such as cave detection at Carlsbad Caverns National Park, a comprehensive hydrogeologic evaluation for slope stability in western North Carolina, a detailed geophysical analysis of karst hazards on the island of Anguilla, delineation of an aquifer and evaluation of water supply production zones in Costa Rica, karst mapping associated with sinkhole investigations throughout Florida, multiple seismic surveys to delineate the depth an integrity of bedrock, and location of underground storage tanks throughout the state of North Carolina.

 

 

Staff Geophysicist

Jeffrey Heenan, Ph.D.

Mr. Heenan acts as one of Pyramid’s main field contacts for the majority of our geophysical projects. He obtained a Bachelor’s degree in Geology from SUNY Oswego in 2009 and his Ph.D. in Environmental Science from Rutgers in 2017. His Ph.D. dissertation, “Geo-Electrical Monitoring of Hydrocarbon Degradation,” utilized electrical geophysical methods to evaluate chemical and physical changes in the subsurface known to result from biodegradation processes. He has been working in the geotechnical and environmental industry for over 5 years performing near-surface geophysical mapping, geotechnical investigations (UST, foundations, site development), environmental site assessments, NCDOT right of way acquisition projects, and water supply investigations. He is an expert in near-surface geophysical methods including Ground Penetrating Radar, Electrical Resistivity, Induced Polarization, and Electromagnetics.
