| Abstract | As part of the Geological Survey of Canada's on-going research on the application of geophysical, mainly electromagnetic, methods in environmental investigations, a ground electromagnetic survey was
conducted at two locations near the Heath Steele mine in New Brunswick. The purpose of the survey was to determine if such surveys are useful for mapping the movement of acid mine drainage from a tailing pond and a stockpile of waste rock containing
sulphide ores from an open-pit operation. Since acid mine drainage is normally more conductive than the surrounding material, its movement in the direction of the hydraulic gradient can form a distinctive plume, which may be detected by a systematic
mapping of ground conductivity in its neighbourhood. The conductive plume was successfully located at one location, but was not detected at the other location. It is suspected that the contaminated fluids moved through fractures in the
bedrock. |
