Electromagnetic Conductivity Mapping

Are you baffled by how one small chemical source area impacted your entire site? Are you looking to locate the extents of impacted soils across your site? Could your site contain areas of buried metallic and non‑metallic waste? A terrain conductivity survey using EM conductivity meters may an option.

We utilize a variety of EM conductivity meters (Geonics EM31, EM34, EM38 and a Geophex GEM-2) to map out shallow variations in geology, locate preferential pathways involved in chemical source migration, and delineate zones of buried fill. These conductivity meters have penetration depths ranging from 5 to 100 feet below ground surface and can be hand carried across smaller, gridded survey areas, or towed on a non-metallic cart behind a utility vehicle for larger sites using a differentially corrected GPS (sub-meter accuracy) to control the data positioning.

From a small parking lot, to entire landfills, we can delineate the subsurface anomalies of your site.
