“…Results of this second demonstration showed that with the use of more advanced data-collection instruments, UXO classification was still possible under these more difficult conditions. Once again, size was the most discriminating feature, separating the medium-to-large UXO from the predominantly small clutter [34]. The third demonstration, held in 2010, was designed to be even more challenging.…”

“…For example, thousands of clutter items were found at both the former Camp Sibert and the former Camp San Luis Obispo [33] [34]. This led to a high statistical confidence in the demonstration results, which were that approximately 30%-50% of anomalies produced by native clutter items could be correctly classified.…”

“…This was not the case for native UXO, however. At the former Camp San Luis Obispo, only 44 native UXO were found in the 10 acres assigned to the demonstration area [34]. Furthermore, zero native UXO were found in the former Camp Sibert's demonstration area [33].…”

“…The 160 selected seed locations were far from each other and far from any native anomaly. When selecting the locations of the seeded UXO, anomalies were avoided since multiple, closely spaced targets, such as a UXO seeded next to a piece of native scrap metal, had generally been difficult to separate and classify in previous classification studies [34]. Analysts at SAIC assisted in determining the minimum spacing between intended seed locations [40] [41].…”

“…However, the results of standardized site demonstrations are not always directly applicable to real remediation projects, as both UXO and clutter are emplaced at the standardized sites according to preconceived notions of which particular types and sizes of targets should be buried at which particular locations, depths, and orientations. Since 2007, then, demonstrations have also been conducted at live sites [33] [34]. Live sites are locations suspected of UXO contamination due to their previous military uses.…”

Their risk of detonation remains, even decades after initial use. Thousands of sites in the United States are suspected of UXO contamination and require remediation. As much as 75% of current remediation costs may be associated with digging up nonhazardous scrap metal called "clutter," instead of UXO. The development, validation, and acceptance of reliable technologies to correctly classify buried targets as UXO or clutter could lead to a significant reduction in UXO remediation costs, allowing more land to be cleared for the same amount of funding.The Environmental Security Technology Certification Program (ESTCP) carried out the third live-site UXO classification demonstration at the former Camp Butner, NC in 2010. The main goal of the demonstration was to test and validate currently available and emerging classification technologies on a live site under operational conditions. Another goal was to involve environmental regulators, program managers, and other stakeholders in the design, execution, and evaluation of the demonstration to better understand what might be required in a real-world remediation project if detected targets were classified as clutter and therefore left in the ground. MethodsThe former Camp Butner was chosen to provide a greater challenge than the previous two demonstration sites. Historical records showed that a variety of munitions had been fired at Butner, including 37 mm projectiles similar in size to clutter. Thus, the estimated size of the buried target was not likely to be a discriminating feature in this demonstration, unlike in the previous two.Although this was a live-site demonstration, 160 inert UXO were seeded at the site, as in the previous two demonstrations. Clutter is common at live sites, but UXO is rare. Additional UXO must be seeded to confidently assess classification capabilities against a well-characterized and statistically significant set of targets.Three ...
