Wide Area UXO Contamination Evaluation by Transect Magnetometer Surveys. Pueblo Precision Bombing and Pattern Gunnery Range No. 2. Victorville Precision Bombing Ranges Y and 15.

摘要

As part of the ESTCP WAA Pilot Project, Nova Research, Inc. conducted a series of vehicular and man-portable geophysical surveys at the Pueblo Precision Bombing and Pattern Gunnery Range No. 2 and the Victorville Precision Bombing Ranges Y and 15 WAA demonstration sites. Transect surveys were conducted using the NRL MTADS magnetometer array and a man-portable EM adjunct along planned transects provided by PNNL in cooperation with SNL and the ESTCP Program Office. Approximately 2% of each site was surveyed using transect plans that were based on available archive information to insure that areas of interest matching the design criteria would be sampled with a statistically defensible probability of detection. These data were analyzed to extract anomaly locations and a measure of the anomaly magnitude using an automated anomaly detection methodology. Total coverage surveys were conducted in small areas at each site to provide additional information. In cases where the geology or terrain of the site limited the use of vehicular-towed magnetometer systems, a man-portable EM system was mobilized.
