MHS employs electromagnetic (EM) surveys, capitalizing on the ground's reaction to fluctuations in electric and magnetic forces induced by conductive materials. This method hinges on generating a primary field by passing alternating current through a coil positioned above the ground. The resulting field disseminates and transforms upon encountering conductive substances beneath the surface. Receivers capture these alterations as data points, subsequently subject to processing to unveil insights regarding the conducting material's geometry and intensity. In environmental investigations, EM instruments assume a pivotal role in gauging the impact of human activities on the Earth. The introduction of inorganic contaminants into the sub-surface, a consequence of human actions, can profoundly alter ground conductivity. EM surveys prove invaluable for delineating the lateral extent of such inorganic influences. Oil and gas facilities extensively employ EM surveys to complement regulatory Environmental Site Assessments. This approach enables non-intrusive determination of environmental impacts, minimizing the need for numerous soil sampling points. Regularly scheduled surveys often track changes over time, enhancing the ability to monitor shifts in the subsurface environment. MHS leverages EM surveys as a versatile tool, providing a comprehensive understanding of subsurface dynamics across various applications.
