INTRODUCTION
The characterization of active military ranges is a critical concern for Army
range managers. Recent lawsuits have sharpened our awareness of the ramifi-
cations of incomplete knowledge when dealing with munition constituents on
training ranges. Of primary concern are the quantity, persistence, and mobility
of the explosives and the by-products of their detonation on groundwater. Char-
acterizing the sources of this possible contamination begins with careful and
thorough sampling.
The U.S. Army Corps of Engineers Cold Regions Research and Engineering
Laboratory (CRREL) and Environmental Laboratory (EL) have worked over
many years developing sampling techniques for explosives residues. As part of
this process, a number of sampling devices have also been developed. These
devices have been evolutionary and are still being improved. In our work,
sampling takes place in two very different environments. This report describes
the tools currently in our arsenal and how we use them in the environments for
which they are designed.
