Use of noninvasive geophysical techniques for the In Situ Vitrification Program

This document is the second volume of a three volume report to evaluate geophysical methods for use in the detailed characterization of waste pits. The In Situ Vitrification (ISV) Program funded the study to support the ISV remediation technology being developed at the Idaho National Engineering Laboratory (INEL). The ISV Program is considering geophysical waste characterization as a means to enhance the efficiency of the ISV process. Field tests were conducted to demonstrate and evaluate the application of magnetic, electromagnetic induction, and ground penetrating radar methods to waste site characterization. The primary objective was to investigate the ability of these noninvasive geophysical methods to locate and identify buried waste materials under conditions representative of the INEL Subsurface Disposal Area (SDA). The tests were conducted at an simulated waste pit designed to represent conditions at the SDA
