Values given are for surface soils except where noted. The following undetected analytes were
excluded from the table: HMX, RDX, 4-amino-2-nitrotoluene, 2-amino-4-nitrotoluene, 1,3-dini-
trobenzene, 1,3,5-trinitrotoluene, 3,5-dinitroanaline, 3,5-dinitrotoluene, 2,4,5-trinitrotoluene, 2,3,4-
trinitrotoluene, 3-nitroaniline.

Locations are distances relative to the muzzle; R = to the right, L = to the left, C = directly in
center front second; distances are from center line.
