Surface Water Quality Associated with the Surface Mining of Iowa Coal

摘要

The production of acid mine drainage has long been a problem associated with the surface mining of coal and typically high levels of sulfur in both coal and shale overburden make this problem particularly acute in Iowa. Interest in the development of the Iowa coal industry and emphasis on environmental protection and the restoration of surface-mined lands were primary objectives of the State of Iowa when the Iowa Coal Project was funded, making the control of water quality an important objective in the operation of the Iowa Coal Project Demonstration Mine No.KICPDM#1).
