The use of electromagnetic (EM) geophysical methods to evaluate ground conductivity variations is an effective tool to resolve environmental issues. However, the EM profiling instruments commonly used (such as the Geonics EM31 ground conductivity meter) for such applications provide depth-averaged conductivity values … [Read more...]
Geophysical Investigation to Identify Buried Infrastructure and Waste
Pyramid Geophysical Services conducted a geophysical investigation across a project site that contained buried waste and exhibited the potential to contain buried infrastructure such as former foundations. Our client wanted to delineate the lateral extent and depths of any buried waste and locate any former foundations … [Read more...]

Electromagnetic Induction and Magnetics Pyramid utilizes in-house electromagnetic geophysical equipment for a wide variety of environmental applications to solve our client's problems. Pyramid utilizes the Geonics EM31 and EM61 systems to perform our electromagnetic induction surveys. The EM31 measures changes in … [Read more...]
Landfill Geophysics
Proper delineation of the extents of buried debris/materials that are associated with landfill sites can be a serious problem for companies that are planning on re-developing the site, or for environmental concerns associated with the buried materials. Geophysical tools can assist in accurately delineating the depth … [Read more...]
Landfill Delineation
North Carolina contains hundreds of properties that served as landfill sites in the past; these former landfills have long since been inactive, and many of the sites are overgrown with no specific knowledge of the extent of the buried waste. In North Carolina, the Department of Environmental Quality (DEQ) has … [Read more...]
