Electromagnetic Geophysical Survey

One of the many tools we have readily available is our soil conductivity meter.  Through the use of electromagnetic induction, this instrument can detect conductivity levels up to an effective depth of five feet.  These results are instantaneous without any requirement for instrument-to-soil contact.

 

It’s most practical application is on a spill-related event.  It can delineate the boundary of the spilled substance (typically salt water) while at the same time indicating the “hot” spots.  The measuring device feeds the information to a GPS-enabled data logger, which integrates the data with coordinates.  This in turn produces a map that can be viewed as three-dimensional or as a contour map.

 

The most significant benefit of the conductivity meter is that it produces instantaneous data; an invaluable feature when quick, informed decisions are necessary.
