Advances In Electromagnetic Methods For Groundwater Studies

In the past decade both inductive electromagnetic survey instrumentation<br>and associated interpretive techniques have become refined to the point that<br>electromagnetic techniques are now widely used for geological mapping as well<br>as for the direct detection of conductive orebodies. Electromagnetic survey<br>techniques have been particularly successful in exploration for potable groundwater,<br>for mapping industrial contaminants in groundwater, for measuring<br>salinity levels in aquifers and monitoring coastal saline intrusion, and for<br>mapping soil salinity in connection with crop growth.
