Values are for surface soils except where noted. The following undetected analytes were excluded from the
table: HMX, RDX, nitroglycerin, 2,5-dinitrotoluene, 3,4-dinitrotoluene. The following analytes were excluded
from the table, but were detected in sample 111 (concentrations are given in parentheses): 2,4,5-trinitrotolu-
ene (69.0), and 2,3,4-trinitrotoluene (17.9). The following analytes were excluded from the table, but were
detected in sample 112, 4-amino-2-nitrotoluene, 2-amino-4-nitrotoluene, 3,5-dinitroanailine, 3,5-dinitrotoluene,
3-nitroaniline.
