Electromagnetic Induction Methods for Monitoring Acid Mine Drainage.
Ground Water Moni Rev 1983 3(1):46-51
In the past 15 yr, surface geophysical methods have found an increasing number of applications in ground water contamination monitoring. More recently, electromagnetic (em) induction methods, long used for mineral exploration, have been added to the suite of geophysical tools readily adaptable to ground water studies. Em surveys are used to measure terrain conductivity, or inverse resistivity. Field operations with em methods are fast and simple, providing a rapid means of obtaining good qualitative data on shallow subsurface conductivity distributions. Successful applications of em surveying have recently been reported for defining landfill leachate plumes and fresh and salt water interfaces. This paper discusses the use of em methods in reclaimed mining site monitoring for three specific field examples.
