USGS Groundwater Information: Branch of Geophysics
OGW BG provides formal and informal geophysical training to USGS offices and cooperators. This page provides an overview of a recent workshop conducted by OGW BG. Because training is customized to address specific interests and needs, each training event is unique.
Geophysical Workshop GW2274C: Borehole and Surface Geophysical Methods for Water-Quality Sampling of Multiple-Zone Wells and Delineation of Fresh/Saline Water Interface, October 31 to November 4, 2005, San Antonio, Texas
In Fall 2005 the USGS Office of Ground Water, Branch of Geophysics (OGW BG) conducted a geophysical methods workshop for the Central Region. The workshop focused on
Borehole geophysical methods discussed included
Surface geophysical methods included
The workshop included hands-on field work in the methods discussed, as well as hands-on computer processing, analysis, and interpretation of the field data collected. Geophysical case studies and field demonstrations focused on boreholes completed in the carbonate Edwards Aquifer and across the associated fresh/saline water interface. Students also had the opportunity to bring their own project case studies for discussion. Workshop participants included USGS ground-water hydrologists as well as cooperator and University scientists.
The subject workshop was sponsored by the Central Region and the Office of Ground Water and was one of a series of workshops that presents principles and techniques for the collection and analysis of geophysical data through lectures, classroom exercises, and field demonstrations in selected aquifer settings across the United States.
