Magnetic Survey of K-Area Bingham Pump Outage Pit
A magnetic survey was conducted at the K-Area Bingham Pump Outage Pit to locate buried metallic construction material placed in the pit. The survey was defined by survey lines spaced 10 feet apart and oriented subperpendicular to the pit elongation direction with survey stations spaced at 5-foot intervals along each line. This arrangement resulted in a 10-foot by 5-foot rectangular grid node pattern. The magnetic survey resolved a linear array of magnetic field and gradient anomalies that result from ferric material buried in the pit. The magnetic survey also resolved other isolated anomalies from ferric sources such as signs and monuments located on the surface. Comparison of the magnetic survey data with radar transects collected in a previous survey indicates that the magnetic anomalies, in most cases, correlate well with diffractions in the radar data. At locations where the anomalies and diffractions do not correlate well, it appears that the radar transect did not pass directly over the anomaly source, resulting in off-line, three-dimensional (3-D) effects in the radar data. Based on the comparison of the two methods, the magnetic data resolves the part of the trench containing the ferrous material; however, the radar data are sensitive to disturbed soil and can resolve the trench boundaries in the absence of buried metallic material.
