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 ...

ESTCP Pilot Program Classification Approaches in Munitions Response Camp Butner, North Carolina

“…All of the results may be found in the report by IDA (Ref. 19). In the following sections, we present selected results that illustrate important conclusions of the demonstration, focusing on what can be achieved with currently available technologies and the value added of emerging advanced sensors and processing.…”

“…(Ref. 19) The report begins with a description of the site and an overview of the program approach. We then describe the detection and classification performance.…”

Joint diagonalization applied to the detection and discrimination of unexploded ordnance

“…A total of 2291 cells were interrogated, of which 171 corresponded to potentially hazardous targets. The discrimination results obtained by our group are published elsewhere (Cazares et al, 2011). Here, we demonstrate only our usage of JD to estimate numbers of targets and illustrate shape differences.…”

“…The results of the Camp Butner blind test were scored independently by the Institute for Defense Analyses (Cazares et al, 2011;SERDP, 2011). We correctly characterized all of the 2291 anomalies, each containing at least one target, for which data were provided.…”

“…All of the 171 potentially dangerous targets were identified as such and also classified by caliber, and our algorithms moreover discriminated between the two kinds of 37-mm projectiles and distinguished the 105-mm HEAT rounds from the other 105-mm shells. We asked for 116 targets to be dug before we were sure that we had identified all the TOI; in contrast, the best analysis using the dipole model required 63 extra digs to reach that level, whereas other procedures needed many more false alarms to be unearthed and in some cases failed to identify UXO (Cazares et al, 2011). One of the stated objectives of the Camp Butner test was to "pave ½ : : : the way for reduced costs and an accelerated timeline to remediate munitions-contaminated sites throughout the nation" (SERDP, 2010).…”
