ERT Survey Electrical Imaging Geophysical Resistivity Meters For Groundwater

Introduction:

One of great advantage of electrical resistivity imaging, is that it can be used to image geologic features from tens of feet to several hundred feet in depth, and still maintain excellent resolution, also has an advantage of having a wide range of resistivity values.

Application:

Hydrogeologic assessments using geophysical resistivity meter. Some examples of groundwater problems include aquifer characterization, groundwater exploration, basin delineation, fracture mapping, karst investigations, aquifer storage and recovery monitoring, plume delineation, and investigating groundwater/surface water interactions
