Time-domain electromagnetic sounding (TDEM), Granite Gravel aquifer

Surface-water/groundwater interactions include the exchange of water, and the chemicals that may be present in the water, which can lead to issues with water supply and water quality. Groundwater can be a major contributor to streams, lakes, and wetlands while surface water can contribute recharge to groundwater. The USGS Oklahoma-Texas Water Science Center (OTWSC) uses geophysics and other...

Geophysical techniques used by the Oklahoma-Texas Water Science Center (OTWSC) provide a relatively quick and inexpensive means to gain insights into how groundwater systems work and the occurrence and distribution of certain contaminants. These techniques are an important tool for scientific investigations, environmental planning, and resource management. Visit the links below for more...
