Geophysical methods can play an important role in dynamic field activities
because they can provide very rapid information about large areas of
a site. This information can be used to select areas requiring further
investigation. They can also be helpful in determining the type of tools
that may be appropriate for collecting samples. Information they provide
may include the location of buried objects, the geologic and hydrogeologic
conditions, and occasionally the location of contaminants. Common geophysical
methods used at hazardous waste sites include: ground penetrating radar,
seismic refraction, electromagnetics, and magnetometry.
