Wide Area UXO Contamination Evaluation by Transect Magnetometer Surveys: Man-Portable EM Demonstration Data Report: Victorville Precision Bombing Ranges Y and 15
Abstract
As part of the Environmental Security Technology Certification Program (ESTCP) Wide Area Assessment (WAA) Pilot Project, Nova Research, Inc. conducted a series of man-portable EMI surveys at the Victorville Precision Bombing Ranges Y and 15, approximately 42 miles southeast of Victorville, CA using a man-portable adjunct of the Naval Research Laboratory (NRL) Multi-sensor Towed Array System (MTADS). 475 anomalies were detected within 14 acres of transect surveys corresponding to coverage of 0.25% of the approximately 5,500 acre site. The survey design plan was designed to expand the site coverage of our earlier magnetometer survey to approximately 2.0% by covering areas not accessible to the tow vehicle during the vehicular survey using the original transect design. The original transect design was prepared by Pacific Northwest National Laboratory and Sandia National Laboratories to allow the tow vehicle to efficiently sample the entire demonstration site while maintaining a statistically defensible probability of traversing areas of interest within the demonstration site that matched the criteria developed from the available archive data and collected in the Conceptual Site Model (CSM). Additionally, 3.3 acres of total coverage surveys were conducted in three small areas (0.75 1 acre per area). The vehicular total coverage areas in the northern portion of the site were found to have much higher magnetic anomaly density, ~250 anomalies/acre, than was seen in the southern portion of the site and had been seen previously at other WAA demonstration sites, 80 anomalies/acre or less. Based on site reconnaissance and considering the geology of the area, the high anomaly density was attributed to magnetically active or hot rocks. One man-portable total coverage area was placed in the vicinity of Target PBR #15 as a control. One hundred and nine (109) anomalies were detected as expected from the validated presence of metallic munitions-related material in the area.
