Abstract : TRW conducted site characterization work at Volunteer Army Ammunition Plant (VAAP) in April and May of 1995, collecting soil phase nitroaromatic contaminant data, then used this data to delineate areas where soil contaminant concentrations and volumes are sufficient to support demonstrations of innovative environmental technology demonstrations. TRW used conventional drilling with a hollow stem auger and split spoon to take discrete soil samples, every 5 feet, down to the water table or a maximum depth of 27 feet. Samples were analyzed for nitroaromatic explosives using a modified EPA method 8330, which calls for High Performance Liquid Chromatography (HPLC). TRW's site 4, the acid fume recovery unit, has both the largest soil volume contaminated with 24DNT (263 yd3) and the largest volume of soil contaminated with all measured analytes (199 yd3). 135TNB and 246TNT have volumes of 121 yd3 and 113 yd3 respectively at TRW site 2 (the wash house) where the TNT was washed at the end of the batch process to remove impurities. TRW site 3 (the bi-house) where the second acid nitration took place, has soil contaminated with 26DNT (104 yd3). The discrete soil sampling at VAAP indicated large lateral and vertical variations in contaminate concentrations.
