Electromagnetic and electrical methods are commonly used in environmental and ground water studies. These methods delineate contamination, locate utilities, detect buried objects and locate major aquifers. The techniques detect electrical property differences between rock, soil, and buried objects. Information is collected rapidly, providing an economical means of surveying large areas.

Electromagnetics

Electromagnetic (EM) methods map conductive objects or areas below the ground surface. EM instruments are light, portable and can cover large areas quickly. EM techniques are particularly useful in mapping regions containing conductive contamination. Electromagnetic techniques are used to:

  • Locate buried metal objects
  • Delineate contamination plumes
  • Map buried trash cells and pits
  • Define lateral changes in lithology
  • Locate water producing fractures
