Application of Statistically-Based Site Characterization Tools to the Pueblo Precision Bombing and Pattern Gunnery Range #2 for the ESTCP Wide Area Assessment Demonstration
Abstract
This report provides results of a subset of the larger wide area assessment project established by ESTCP to field test a number of UXO site characterization technologies. Pacific Northwest National Laboratory (PNNL) and Sandia National Laboratories (SNL) have developed statistical algorithms to create transect designs based on desired Data Quality Objectives (DQO) and identify potential target areas. The transect design tools provide a statistically defensible method to use transect survey data that covers only a small proportion of the total study area (i.e. 1% to 3%) to identify target areas of a desired size, shape and anomaly density. Target area density estimates, probability estimates, and density flagging routines are applied after the data are gathered from the established transect design to separate potential target areas from areas that require no further remediation. These tools, combined with the other components of the wide area assessment (WAA) project, can provide methods to correctly and efficiently aide in the transfer of formerly used defense sites (FUDS) to the public or private domain. This report documents the application of statistically-based site characterization tools developed by PNNL and SNL to the Pueblo Precision Bombing and Pattern Gunnery Range #2 as part of the ESTCP WAA. Specifically, these tools are used to accomplish: 1) geophysical transect design to locate potential target areas with an agreed upon confidence; 2) anomaly density estimation across the site using the geophysical transect data collected along the transect design; and 3) target area boundary delineation. These activities are conducted for several different conceptual site models accounting for multiple types of munitions thought to be used at the site.
