Ground Penetrating Radar

Stratigraphy & Contamination Detection
Ground penetrating radar (commonly called GPR) is a geophysical method that has been developed over the past thirty years for shallow, high-resolution, subsurface investigations of the earth. GPR uses high frequency pulsed electromagnetic waves (generally 10 MHz to 1,000 MHz) to acquire subsurface information. Energy is propagated downward into the ground and is reflected back to the surface from boundaries at which there are electrical property contrasts. GPR is a method that is commonly used for environmental, engineering, archeological, and other shallow investigations.

Environmental Investigations:
Detection of pipes, drums, barrels, and other metallic and non-metallic objects
Detection of hydrocarbon contamination
Delineation of vertical and horizontal extent of buried landfills

Geologic Investigations:
Soil lithology
Depth to bedrock
Permafrost detection
Groundwater investigation
Fast and cost effective
Non-Intrusive and Non-Hazardous
Operational in arctic environments
