USGS VAWSC Warren County Geophysics

Borehole and surface geophysical data have been collected in Warren County to provide insight into the nature of fracturing, to aid in the development of the hydrogeologic framework, and to investigate ground water/surface water interactions.

	Borehole geophysical logging ()-- Standard borehole logging methods (caliper, gamma, single and multi-point resistance, self potential, fluid temperature and resistivity) along with electromagnetic (EM) induction, acoustic and optical televiewer, borehole video camera, and borehole deviation are being used to investigate hydrogeologic unit contacts, fracturing, and water-bearing properties.
	Surface geophysics ()-- Marine continuous resistivity and multi-frequency domain electromagnetic have been measured along the South Fork of the Shenandoah River and the Shenandoah River to investigate ground water and surface water interactions.
Additional information on geophysical techniques used in hydrologic investigations is available at the U.S. Geological Survey, Office of Ground Water, Branch of Geophysics (http://water.usgs.gov/ogw/bgas/)
