Electromagnetic Surveys

Electromagnetic conductivity (also known as terrain conductivity) measures the conductivity of the subsurface which includes soil, groundwater, rock, and objects buried in the ground.

Electromagnetic conductivity surveys can be carried out quickly. The EM instruments are easily carried around the site and are used for a variety of applications.

Underground metal petroleum tanks can be located, metal underground utility pipes can be detected, contaminated groundwater can be mapped, and clay units can be identified.

Applications of Electromagnetic Conductivity include:

buried metallic objects
underground metal storage tanks and drums
buried metal utility lines
landfills and trenches
contaminant plumes
bedrock fractures
mining and minerals
archaeology
