month. Several older craters varying in age from months to years and produced
by variously sized artillery and mortar impacts were also sampled.
The sampling of craters generally consisted of collecting surface soil
randomly around the rim, around the inside sloping surface, and at the bottom.
With the assistance of the EOD team, several soil samples were collected around
and below a low-order detonation of a 155-mm artillery round. Three surface soil
samples were collected around a low-order 120-mm mortar round. Several
samples and the associated surface organic matter were collected in areas that
were overgrown with vegetation and had no apparent disturbance within several
meters. Numerous surface soil samples and some depth samples were collected
as deemed appropriate. Five areas were sampled using the wheel sampling
scheme described earlier. Some of these areas were centered over a crater and
some were between craters. A total of 70 samples were collected within the
artillery impact area.
