Electrical Resistivity Methods for Borehole Siting in Hardrock Region

  • Ron D. Barker


The measurement of earth resistivity is the most commonly employed geophysical technique in hydrogeological investigations but is perhaps one of the least well understood. The ease with which electrical measurements can now normally be made has led many non-geophysicists to believe, quite falsely, that resistivity is simple. Unfortunately this has led to many common errors in field practice and interpretation and ultimately to the production of ubiquitous, poor quality, survey reports. Inevitably this has resulted in the often poor reputation of this technique which is unfortunate because used correctly the resistivity technique is one of the most cost-efficient and powerful of the geophysical tools. This article outlines the principles of the techniques now in common use and shows how the results should be interpreted to obtain the most useful subsurface information
