Abstract:
|
Currently, millions of acres of formerly used Department of Defense sites (FUDS) contain or may contain munitions or explosives of concern (MEC), such as unexploded ordnance (UXO). In an effort to reduce costs of finding UXO target areas and assessing the degree of confidence in UXO clean-up efforts, the Statistical Sciences group at the Pacific Northwest National Laboratory developed two UXO modules in the Visual Sample Plan (VSP) software (available free at http://dqo.pnl.gov/vsp). We explore how a Monte Carlo simulation gives the probability of detecting a target area as a function of transect spacing and the density of anomalous geophysical-detector readings in the target area. We also apply compliance sampling to MEC clean-up using a Bayesian and/or frequentist framework. A demonstration of how these modules are being used on FUDS lands will be given.
