Various geophysical methods can be used to delineate the location of specific underground objects or remains that may be of interest to principal parties, environmental scientists, archeologists, law enforcement, and civil engineers. Applicable geophysical methods include magnetometer, ground penetrating radar, electromagnetic and utility locating methods. The results of these geophysical investigations can supplement:
Environmental auditsthat must verify the existence of underground storage tanks, utilities, buried debris, and other subsurface facilities, and for the planning of subsequent investigations
Invasive investigationsincluding drilling, sampling, and probing that must avoid obstructions such as utilities, tanks, and other subsurface features that may be a potential drilling hazard
Archeological surveysto locate historic objects, structures, and human remains
Forensic investigationssearching crime scenes for discarded or hidden objects, human remains, etc.
