Ground penetrating radar (GPR) can be used in appropriate geological s
ettings to help map subsurface geological structures and groundwater c
ontaminants. Associated engineering and environmental applications are
numerous. In particular, GPR surveys can help to identify the approxi
mate boundaries of contaminant plumes and provide stratigraphic inform
ation at a site. Case studies from sites in Arizona and Utah show that
goad correlation exists between GPR signatures and hydrocarbon contam
ination in strategically located wells. GPR data can also be very usef
ul in identifying shallow faulting, and the characteristics of the ass
ociated subsurface deformation can be used to gain a better understand
ing of the potential for surface ruptures at a site. An example from a
long the Wasatch Fault Zone, Utah County, Utah, shows good correlation
between GPR data and trench data. Finally, examples from Prove, Utah
and Eureka, Utah demonstrate the utility of using GPR for locating und
erground excavations and/or cavities.
