In order to characterize the concentration of dust flowing inside a duct, a measured amount of dust must be extracted over a known period of time. This collection velocity must be the same as the internal duct flow velocity to avoid altering the distribution of dust particle sizes. In addition, a number of sample points over the entire duct cross sectional area is necessary to define the overall dust concentration. This method of sampling, known as gravimetric sampling under isokinetic conditions, was used to determine the dust concentrations at the various manufacturing areas in the Army Ammunition Plants. 

The test plan that was executed at Holston Army Ammunition Plant (HAAP) demonstrated that the hydrolysis process for the energetic materials of interest successfully destroyed more than 99.7 percent of the energetics treated. Over 9,500 pounds of energetic materials were destroyed while encountering only the types of problems normally expected during the implementation of a new facility and process. The suite of tests performed at Los Alamos National Laboratory (LANL) and at HAAP covered a range of reaction temperatures and caustic concentrations. Under all these conditions, the destruction of energetics was carried out safely and effectively. 

TNB was detected in water from on-site and off-site wells at maximum concentrations of 352 and 114 ppb, respectively, at the Cornhusker Army Ammunition Plant (CAAP) near Grand Island, Nebraska (ATSDR 1989a). CAAP is an NPL site CAAP is not currently producing or storing... 

Based on the U.S. Department of Defense s (DOD s) pilot-scale demonstration at the Volunteer Army Ammunition Plant in Chattanooga, Tennessee, ECOCHOICE is capable of reducing the concentrations target contaminants to less than 3 ppb. At a flow rate of 24 million gallons of contaminated groundwater per year, treatment costs would average 3.00 per 1000 gal (D20947M, p. 2). 

Tetryl has been detected in groundwater beneath artificial leaching pits located at the Louisiana Army Ammunition Plant at concentrations ranging from 1.4 to 53 pg/L (Army 1988). 

No tetryl was detected (detection limit of 20 pg/L) in samples from 44 groundwater sites, 23 surface water sites, or 5 treatment lagoons located at the Milan Army Ammunition Plant in Tennessee (Army 1980). In addition, sediment samples from the 5 lagoons did not show tetryl to be present (detection limit of 90 pg/L). Tetryl was detected in groundwater samples taken at the Iowa Army Ammunition Plant at a maximum concentration of 49 pg/L it did not exceed the level of detection (2.9 pg/L) in any surface water samples (Army 1982c). 

Tetryl was detected in sediment samples taken at the Iowa Army Ammunition Plant at a maximum concentration of 33 pg/gram (Army 1982c). However, all soil samples were below the level of detection (2 pg/gram). 

No data are available regarding levels of RDX in outdoor air. However, indoor air samples collected at Holtson Army ammunition plant in Kingsport, Tennessee in 1974 contained RDX levels ranging from not detected (<0.5 mg/m [4.5 ppm]) to 60 mg/m (546 ppm (Army 1975). A more recent study found that RDX was detected at a concentration of 0.032 mg/m (0.29 ppm) in the particulate fraction of one indoor air sample taken from the incorporation area of Holtson Army ammunition plant in 1986 (Bishop et al. 1988). 

Ocean floor sediment samples taken in 1971 from a munitions dumping area 85 miles west of Cape Flattery, Washington, and similar samples taken 172 miles south-southeast of Charleston, South Carolina, were analyzed for RDX (Navy 1972). No RDX was found in any of the sediment samples analyzed. RDX was found on-site at the Savanna Army Depot in Illinois in soil samples at a maximum concentration of 12.3 ppm (ATSDR 1989c). RDX was found at the Louisiana Army ammunition plant in soil and drainage sediments at concentrations ranging from <5 to 602 mg/kg (Army 1988). 

It has been recommended that a maximum allowable TNT concentration in drinking water be set at 140 ppb and the U.S. Environmental Protection Agency has calculated a lifetime health advisory of 2 ppb TNT in drinking water (70, 71). The cleanup criterion recommended by the U.S. Army is 5 ppm for TNT-contaminated soils at inactive army ammunition plants (69). Thus, there is a clear need to develop TNT remediation procedures for water and soil.
