Geophysical Characterization

Surface and borehole geophysical characterization of ground-water contamination

The USGS Toxic Substances Hydrology (Toxics) Program conducts geophysical investigations and applied research at a variety of the Program’s research sites. In most cases geophysical activities complement and extend the other research activities at the sites. The objectives of the work are to use geophysical methods to characterize and monitor the processes and properties that affect the migration of a diverse set of contaminants in the subsurface and to develop and modify geophysical methods for the detection, characterization, and monitoring of subsurface contamination. Emphasis is placed on providing increasingly quantitative spatial and temporal information about subsurface structure and the distribution of contaminants. The Toxics Program disseminates the results of this research to environmental professionals through publications, presentations, and technology transfer and training programs. The information presented on this page cuts across lines drawn by individual investigations and projects so that information on the application of geophysical methods to contaminant studies can be presented in one place.
