Buried Debris Study
Buried debris surveys are typically conducted using Ground Penetrating Radar (GPR) and depending on the suspected depth of the debris, Time Domain Electromagnetics (TDEM) or Frequency Domain Electromagnetics (FDEM). The difference between the TDEM and the FDEM is not only depth but the FDEM can simultaneously record readings of elevated metallic response and changes in soil conductivity. If the suspected target is metallic, such as buried drums, and is within the top 6 to 8 feet below land surface (bls) TDEM is the ideal coupling with GPR. If the target is a mix of non-metallic and small metallic objects that are within the top 10 feet bls, the FDEM teamed with the GPR provide a quality result.
