Values given are for surface soils except where noted. The following undetected analytes were excluded from the
table: HMX, RDX, 4-amino-2,6-dinitrotoluene, 2-amino-4,6-dinitrotoluene, 1,3-dinitrobenzene, 1,3,5-
trinitrobenzene, 3,5-dinitroanaline, 3,5-dinitrotoluene, 2,4,5-trinitrotoluene, 2,3,4-trinitrotoluene, 3-nitroaniline.
2
Locations are distances relative to the muzzle of the gun: R = to the right, L = to the left, C = directly in center
front second; distances are from center line.
3
Less than detection limits.
4
Values are trace below mean detection limits (see Table 2).
