Blossom Point Marine Transect Survey Statistical Analysis with Visual Sample Plan

Abstract

The Environmental Security Technology Certification Program (ESTCP) has been evaluating several site characterization technologies for unexploded ordinance (UXO) site characterization. One of those ESTCP sponsored technologies developed by PNNL and SNL includes statistical algorithms that use the data quality objective structure to create appropriate sparsely spaced transect designs and then analyze these surveyed transects to identify potential target areas within the surveyed area. These transect design and mapping tools provide a statistically defensible method that uses transect survey data from a small proportion of the total study area (i.e., 1 to 3 percent) to identify target areas of a specific size, shape, and anomaly density. Target area density estimates, target probability estimates, and density flagging routines are applied after the surveys are performed to separate potential target areas from areas that require no further remediation. These methods have been deployed within the Visual Sample Plan (VSP) software tool. Evaluations and demonstrations of several integrated land-based characterization technologies have been documented in reports about previous Wide Area Assessment demonstration sites in Colorado, Ohio, and California (Roberts et al. 2007; Hathaway et al. 2006, 2007, 2008). In addition, ESTCP has been evaluating and demonstrating underwater site characterization technologies. One demonstration involved an underwater site along the Potomac River adjacent to the U.S. Army s Blossom Point Field Test Facility in Maryland. An underwater geophysical transect survey was designed and conducted by the ESTCP team and contractor. The PNNL/SNL team was then asked to use the target area flagging, anomaly density mapping and estimation, and target area delineation tools within the VSP software to perform an analysis of the survey results.
