GEOPHYSICAL PROFILING IN SUPPORT OF A NITRATE AND URANIUM GROUNDWATER REMEDIATION STUDY

Multielectrode resistivity methods and pseudo-tomographic seismic refraction techniques were used to image to a depth of approximately 30m at the Field Research Center, a research site that has been developed by the U. S. Department of Energy to study bioremediation methods. The site is known to contain nitrates, uranium, and other contaminants. The geophysical methods were effective in defining the plume and in defining geologic units that appear to influence contaminant transport. Extensive drilling and groundwater sampling verified the geophysical data.
