Why choose geophysics in the engineering and environmental fields?

A client calls and needs you to find voids under an airport runway in a hurry. Your firm needs to delineate the boundaries of a contaminant plume that is thought to be flowing from a landfill. In situations like these, the job needs to be done quickly and efficiently. That's the benefit of geophysics. No matter what the application, there are a variety of geophysical methods available. Geophysical surveys can provide an accurate, timely answer to questions concerning the environment or engineering with a minimum amount of disturbance to the surface of your site. In essence, geophysics allows you to "see below the surface" without having to excavate large areas or drill as many boreholes.
