Current applications of geophysical techniques to environmental
problems are typically documented in proceedings volumes of the annual
Symposium on the Application of Geophysics to Engineering and Environmental
Problems (SAGEEP) [ Anonymous, 1991; Bell,
1992; Bell and Lepper, 1993, 1994]. Ground-penetrating
radar (GPR) applications are found in the proceedings of the biennial
International Conference on Ground Penetrating Radar
[ H
nninen and Autio, 1992;
Anonymous, 1994]. Many of these publications are
unrefereed. To a lesser extent, examples are found in standard geophysical
journals (e.g. Geophysics, Geoexploration, Journal of Applied
Geophysics, and The Log Analyst). Journals devoted to ground-water
topics (e.g. Ground Water, Ground Water Monitoring Review, and
Water Resources Research) also contain occasional geophysics
papers. For an extensive review of geophysical techniques and their
application to environmental problems see Boulding
[1993]. Although they are outside of the time frame of this review,
it is worth mentioning the three volumes edited by Ward
[1990], which contain tutorials on geophysical techniques applicable
to environmental studies as well as many environmental case histories.
The following examples of geophysical applications, categorized by
problem area, are typical; many other examples exist.
