National Technical Reports Library

The National Technical Information Service acquires, indexes, abstracts, and archives the largest collection of U.S. government-sponsored technical reports in existence. The NTRL offers online, free and open access to these authenticated government technical reports. Technical reports and documents in its repository may be available online for free either from the issuing federal agency, the U.S. Government Publishing Office’s Federal Digital System website, or through search engines.

Results of the Application of Seismic-Reflection and Electromagnetic Techniques for Near-Surface Hydrogeologic and Environmental Investigations at Fort Bragg, North Carolina.

PB97173090

Publication Date	1997
Personal Author	Meyer, M. T.; Fine, J. M.
Page Count	52
Abstract	This report summarizes the application and usefulness of shallow seismic-reflection and electromagnetic techniques in a variety of geologic and environmental settings commonly encountered at Fort Bragg, North Carolina, particularly in the cantonment area where most of the potentially contaminated sites are located. For this investigation, two shallow seismic-reflection techniques (compression (P) and shear (S) wave) and two electromagnetic techniques (ground-penetrating radar (GPR) and terrain conductivity) were tested at two sites used for background sampling for the RFI's at the Base. Two electromagnetic techniques, GPR and terrain-conductivity, also were evaluated for use in delineating the areal extend and depth of landfills at three SWMU's and a buried fuel tank at a location identified as an areas of concern (AOC) at Fort Bragg. Terrain conductivity tests were conducted with the Geonics EM31 and EM34.
