Abstract (summary)

The research project was designed to apply magnetic mapping geophysical investigative techniques to the determination of the magnetic properties of 55-gallon cold-rolled carbon steel hazardous waste drums and to utilize these magnetic properties to locate buried drums. Cold rolled carbon steel exhibits ferromagnetism; so two experimental designs were completed to investigate the ferromagnetic properties of the 55-gallon drums that are commonly used in the collection, transportation, storage, and final disposal of hazardous waste. These ferromagnetic properties are the magnetic pole strength, magnetic moment, induction, permeability, and magnetic susceptibility.

For purposes of this study, a new geophysical detection device has been developed that integrates handheld fluxgate magnetometers with a two-directional inclinometer and an automatic datalogger. This new measurement and data collection system allowed the collection of the three-dimensional vector magnetic field simultaneously with magnetometer sensing head inclination. This combined data allows for the resolution of the three dimensional vector data to a consistent horizontal and vertical plane. This new and mobile system has been tested in several experiments to determine the ferromagnetic properties of a typical drum for the first time and also to measure the magnetic field in a typical geophysical site investigation.
