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...]

Landfill Geophysics
Landfill Characterization - Utilizing geophysics to identify buried waste/debris 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 … [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...]
