Technical Memorandum on Surface Geophysical Surveys, High Priority SWMUs
Section 10 - Summary of Geophysical Results
Surface geophysical surveys were performed at a total of eight sites to investigate high priority SWMUs at CSSA. EM surveys were conducted at all eight sites, and GPR surveys were conducted at two sites. EM anomalies were detected at the following four SWMUs: B-8, B-15/16, B-23A, and B-24. In addition, GPR anomalies were detected at B-15/16 and B-24. The following table lists the total number of anomalies detected at each high priority SWMU by surface geophysical methods:
