The most common methods used for locating a landfill are the geophysical methods of electromagnetic conductivity (EM) and ground penetrating radar (GPR). Photographs showing how these geophysical survey methods are conducted and the results that can be obtained are shown below:
Electromagnetic Conductivity Surveys for Locating Landfills and Trench Debris
Above are the shallow EM conductivity meter (white pole) and the deeper EM conductivity meter (hoops)

The instruments shown above can locate buried trenches, landfills, and inorganic or salt plumes. The shallow EM conductivity meter locates metal and measures ground conductivity to a depth of 20 feet (6 m). The EM metal detector locates metal to 10 feet and can more accurately define the metal target locations than the shallow EM conductivity meter. The deeper EM conductivity meter can measure ground conductivity to 100 feet (30 m). The EM conductivity instruments are excellent for locating inorganic and salt plumes from landfills and waste pits.
The map (above) shows the results of a survey conducted with GeoModel, Inc.'s EM ground conductivity meter. Areas of former trenching can be seen in blue and buried metal can be seen in red and orange.
Ground Penetrating Radar (GPR) Surveys
GeoModel, Inc. can conduct ground penetrating radar (GPR) for buried trench and landfill location. The 200 MHz antenna (seen below) was used to obtain the data on two trenches. The antenna can be pulled by hand, ATV, or truck.
Two Landfill Trenches
GeoModel, Inc. was founded in 1991 as a geophysical services and environmental consulting firm. The company principals have over 50 years of combined experience and have conducted numerous EM, GPR, and resistivity surveys for landfill location, including landfill cells, trenches, and plumes. All projects are conducted by registered professional geologists.
