Heavy-metal contamination on training ranges at the Grafenwoehr Training Area, Germany

Description: Large quantities of lead and other heavy metals are deposited in the environment of weapons ranges during training exercises. This study was conducted to determine the type, degree, and extent of heavy-metal contamination on selected handgun, rifle, and hand-grenade ranges at Grafenwoehr Training Area, Germany. Soil, vegetation, and surface-water samples were collected and analyzed using the inductively-coupled plasma atomic-emission spectroscopy (ICP-AES) method and the toxic characterization … more

Clinical $sup 13$CO$sub 2$ breath tests: methodology and limitations

Description: Methods were developed to perform $sup 13$CO$sub 2$ breath tests and the limitations and sources of error in these tests were explored. The random error introduced during each step of the analysis was determined and it was found that the precision was limited by the fluctuations in the isotope ratio of the patient's endogenous CO$sub 2$. The detection limit was a 1.4 percent increase in the isotope ratio. This corresponds to an oxidation rate of 140 nmoles/kg-hr of singly labeled substrate to C… more

Uptake of explosives from contaminated soil by existing vegetation at the Joliet Army Ammunition Plant

Description: This study examines the uptake of explosives by existing vegetation growing in TNT-contaminated soils on Group 61 at the Joliet Army Ammunition Plant (JAAP). The soils in this group were contaminated more than 40 years ago. In this study, existing plant materials and soil from the root zone were sampled from 15 locations and analyzed to determine TNT uptake by plants under natural field conditions. Plant materials were separated by species if more than one species was present at a sampling loca… more

Plant uptake of explosives from contaminated soil at the Joliet Army Ammunition Plant

Description: Explosives and their degradation products may enter the animal and human food chains through plants grown on soils contaminated with explosives. Soil and plant samples were collected from the Group 61 area at the Joliet Army Ammunition Plant and analyzed to determine the extent to which 2,4,6-trinitrotoluene (TNT) and its degradation products are taken up by existing vegetation and crops growing on contaminated soils. Neither TNT nor its degradation products was detected in any of the abovegrou… more

Uptake of explosives from contaminated soil by vegetation at the Joliet Army Ammunition Plant

Description: This study examines the uptake of explosives by vegetation growing on soils contaminated by 2,4,6-trinitrotoluene (TNT) in Group 61 at the Joliet Army Ammunition Plant (JAAP). Plant materials and soil from the root zone were sampled and analyzed to determine TNT uptake under natural field conditions. Standard USATHAMA methods were used to determine concentrations of explosives, their derivatives, and metabolites in the soil samples. No- explosives were detected in the aboveground portion of any… more

X-ray fluorescence investigation of heavy-metal contamination on metal surfaces in the Pilot Plant Complex, Aberdeen Proving Ground, Maryland

Description: A field program using a portable x-ray fluorescence (XRF) instrument was carried out to obtain data on loadings of RCRA-regulated heavy metals in paint on metal surfaces within the Pilot Plant Complex at Aberdeen Proving Ground, Maryland. Measured loadings of heavy metals were sufficiently small that they do not present problems for either human exposure or the disposition of building demolition rubble. An attempt to develop an external calibration of the XRF instrument for cadmium, chromium, a… more

Evaluation of Field-Portable X-Ray Fluorescence Spectrometry for the Determination of Lead Contamination on Small-Arms Firing Ranges

Description: Field analytical methods for the characterization of lead contamination in soil are being developed. In this study, the usefulness of a commercially available, field-portable energy-dispersive X-ray fluorescence spectrometer (XRF) is evaluated for determining the extent of lead contamination in soils on small-arms firing ranges at a military installation. This field screening technique provides significant time and cost savings for the study of sites with lead-contaminated soil. Data obtained w… more

Uptake of explosives from contaminated soil by existing vegetation at the Iowa Army Ammunition Plant

Description: This study examines the uptake of explosives by existing vegetation growing in soils contaminated with 2,4,6-trinitrotoluene (TNT) and 1,3,5-trinitro-3,5-triazine (RDX) in three areas at the Iowa Army Ammunition Plant (IAAP). To determine explosives uptake under natural environmental conditions, existing plant materials and soil from the root zone were sampled at different locations in each area, and plant materials were separated by species. Standard methods were used to determine the concentr… more

Remediation of heavy-metal-contaminated soil using chelant extraction: Feasibility studies

Description: Results are presented of a laboratory investigation conducted to determine the efficacy of using chelating agents to extract heavy metals (Pb, Cd, Cr, Ba, Cu, and Zn) from soil, the primary focus being on the extraction of lead from the soil. Results from the batch-shaker studies and emphasizes the columnar extraction studies are described. The chelating agents studied included ethylenediaminetetraacetic acid (EDTA) and citric acid, in addition to water. Concentrations of the chelants ranged fr… more

X-ray fluorescence investigation of surface lead in the Pilot Plant Complex, Aberdeen Proving Ground, Maryland

Description: This report presents the results and findings from a field measurement program undertaken in the Pilot Plant Complex (PPC) at Aberdeen Proving Ground, Maryland, to address the potential contamination of the PPC structures with lead in paint. A portable x-ray fluorescence device was used to measure the lead loading at approximately 1,000 locations on painted surfaces in the PPC buildings. The device performed well, although external calibration was necessary for accurate results. The principal c… more

Monitoring for PCBs at the Pilot Plant Complex, Aberdeen Proving Ground

Description: The US Army`s Aberdeen Proving Ground has been a test site for a variety of munitions, including chemical warfare agents. The Pilot Plant Complex (PPC) at Aberdeen was the site of the development, manufacture, storage, and disposal of a number of chemical warfare agents. The objective of this study was to determine if there is polychlorinated biphenyl (PCB) contamination in the PPC. The results of screening done by Argonne indicate that PCBs in the air of the PPC are well below acceptable level… more

Toxics testing performance evaluation for GB and GD

Description: Residues resulting from demilitarization, treatment, cleanup, and testing of military chemical agents at Dugway Proving Ground (DPG), Utah, are currently listed as hazardous wastes by the State of Utah Department of Environmental Quality. The US Army Test and Evaluation Command believes that certain categories of waste generated at DPG are not hazardous. To demonstrate this, analytical methods capable of quantitatively measuring the concentrations of chemical agents, including GB and GD, in the… more

Air monitoring for volatile organic compounds at the Pilot Plant Complex, Aberdeen Proving Ground, Maryland

Description: The US Army`s Aberdeen Proving Ground has been a test site for a variety of munitions, including chemical warfare agents (CWA). The Pilot Plant Complex (PPC) at Aberdeen was the site of development, manufacture, storage, and disposal of CWA. Deterioration of the buildings and violations of environmental laws led to closure of the complex in 1986. Since that time, all equipment, piping, and conduit in the buildings have been removed. The buildings have been declared free of surface CWA contamina… more

Using Phytoremediation to Clean Up Contamination at Military Installations

Description: During and following World War II, wastes from the production of munitions and other military materials were disposed of using the best available practices acceptable at that time. However, these disposal methods often contaminated soil and groundwater with organic compounds and metals that require cleanup under current regulations. An emerging technology for cleaning contaminated soils and shallow groundwater is phytoremediation, an environmentally friendly, low- cost, and low-tech process. Ph… more
