Geophysical Support
Geophysics
can provide you...
with a cost effective safe method to remotely investigate and define the subsurface conditions of a site. By measuring the physical, electrical, and geochemical properties of subsurface materials, geophysical surveys can be used to characterize the geology and hydrogeology of a site as well as locate buried man-made features. The Field Support Section can provide technical assistance, field support, and oversight in the use of geophysical methods in the characterization of hazardous waste, oil spill, and Brownfield sites.
