Surface Geophysical Investigations for Hazardous Waste Sites

Source

Surface geophysical surveys provide regional and site-specific subsurface information for hazardous waste investigations. The surveys can be used: (1) during the reconnaissance phase of an investigation, (2) for obtaining detailed site-specific information, and (3) for monitoring purposes after detailed investigations have been completed.

The choice of the geophysical method used in a survey depends on: (1) a knowledge of the geologic and hydrologie conditions and (2) the type of contaminant and its suspected depth. The different methods measure different physical properties which can be interpreted as geologic features or, if the target is man-made, as cultural features. The ambiguity inherent in geophysical methods can be reduced by conducting two or more surveys that measure different physical properties.
