Track that spill

摘要

The answer to this challenge is more straightforward than it might appear at first.There are some simple things that you or an environmental consultant can do to locate the spill quickly and relatively inexpensively.The first is a geophysical survey.The technique requires a moderately expensive transmitter/receiver to measure electrical conductivity in the ground.The equipment is portable and relatively easy to use,but you might want to hire a trained operator to interpret the results.Two or three types of transmitters/receivers are commercially available for rental.
