Conductivity / EM31

Conductivity mapping with the EM31 system allows for quick surveying and rapid data acquisition.  It is a near-surface electromagnetic technique that measures the ability of subsurface materials to allow electricity to flow and thus, map the apparent lateral conductivity variations in underlying materials.  For geological and environmental application BRG can use the EM31 data to map overburden type and thickness, variations in depth to bedrock, sinkholes or karst terrain, underground storage tanks, pipes, culverts and possible groundwater contamination plumes.
