“…The authors found that in terms of metal input into the environment, there remains a limited number of extensive studies that pertain specifically to larger caliber artillery and mortar ranges in literature with the majority of studies focusing on energetic compounds from such activities (Brannon et al, 2000;Jenkins et al, 2001Jenkins et al, , 2006Pennington et al, 2008;Thiboutot et al, 2012). More recently, Clausen et al (2012) conducted a study of four Army pyrotechnic devices heavily used during range training to assess the metal deposition rate. The study concluded salts of Ba, Cu, Mn, K, and Sr were introduced into the environment.…”

The deposition of metals into the environment as a result of military training activities remains a longterm concern for Defense organizations across the globe. Of particular concern for deposition and potential mobilization are antimony (Sb), arsenic (As), copper (Cu), lead (Pb), and tungsten (W), which are the focus of this review article. The fate, transport, and mobilization of these metals are complicated and depend on a variety of environmental factors that are often convoluted, heterogeneous, and site dependent. While there have been many studies investigating contaminant mobilization on military training lands there exists a lack of cohesiveness surrounding the current state of knowledge for these five metals. The focus of this review article is to compile the current knowledge of the fate, transport, and ultimate risks presented by metals associated with different military training activities particularly as a result of small arms training activities, artillery/mortar ranges, battleruns, rocket ranges, and grenade courts. From there, we discuss emerging research results and finish with suggestions of where future research efforts and training range designs could be focused toward further reducing the deposition, limiting the migration, and decreasing risks presented by metals in the environment. Additionally, information presented here may offer insights into Sb, As, Cu, Pb, and W in other environmental settings.

Military ranges are unlike many waste sites because the contaminants, both energetics and metals, are heterogeneously distributed in soil during explosive detonation or ballistic impact and cannot be readily characterized using conventional grab sampling. The Incremental Sampling Methodology (ISM) has been successful for characterization of energetic contamination in soils, but no published ISM processing studies for soils with small arms range metals such as Pb, Cu, Sb, and Zn exists. This study evaluated several ISM sample-processing steps: (1) field splitting to reduce the sample mass shipped to the analytical laboratory, (2) necessity of milling, and (3) processing a larger subsample mass for digestion in lieu of milling. Cone-and-quartering and rotary sectorial splitting techniques yielded poor precision and positively skewed distributions. Hence, an increase in digestion mass from 2 to 10 g was evaluated with milled and unmilled samples. Unmilled samples yielded results with the largest variability regardless of aliquot mass.
