Electromagnetic Conductivity (EM)

(Terrain Conductivity) 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. Our company has conducted numerous electromagnetic conductivity (EM) surveys worldwide using EM-31 and EM-34 instruments for various applications.

Electromagnetic conductivity (terrain conductivity) surveys are rapid and very accurate. The EM instruments are easily carried around the site and are used for a variety of purposes. Underground petroleum tanks can be located, contaminated groundwater can be mapped, and clay units can be identified.

Our geophysicists can perform an EM survey anywhere in the world and with short notice. Electromagnetic conductivity survey costs are reasonable.

• buried metallic objects
• tanks, drums, utility lines
• landfills and trenches
• unexploded ordnance
• contaminant plumes
• bedrock fractures
• mining and minerals
• archaeology
