Values given are for surface soils except where noted. The following undetected analytes were excluded from the table: 4-amino-2-nitrotoluene, 2-
amino-4-nitrotoluene, 1,3-dinitrobenzene, nitroglycerin, 2,5-dinitrotoluene, 3,4-dinitrotoluene, 3,5-dinitrotoluene, 2,4,5-trinitrotoluene, 2,3,4-
trinitrotoluene, 3-nitroaniline.
2
Locations give distance from reference wall separating impact areas for each range and depth in cm if sample was not taken at the surface.
3
Trace detected below mean detection limit.
4
Less than detection limits.
5
Wheel pattern of sampling, C = center of wheel; A-F clockwise around wheel circumference.
6
Center, bottom of crater.
7
Rim, composite.
8
Center.
