Locating tanks, barrels and buried trash is the most common use of civil and environmental geophysics. Magnetic methods locate metal objects such as buried tanks and barrels. Magnetics provides a scaled map of all the metal buried at a site. We can often tell what an object is from its magnetic signature. We augment magnetics with a ground penetrating radar. At many sites, the radar provides "pictures" of buried objects. The radar can also detect nonmetal objects. Electromagnetic (EM) and resistivity techniques are used to locate nonmetal waste such as household debris, saltwater contamination and old acid ponds. Both EM and resistivity provide maps and two-dimensional views of buried waste. Better information on what is underground promotes better clean up.
