폐탄광 부근 지하수의 오염에 관한 연구
Abstract
Sampling of waters from each stage of treatment system, SAPS (Successive Alkalinity Producing System), and spring water near the Hanchang coal mine of Kangwon. Province were carried out periodically and analyzed to evaluate the source and possible path of groundwater contamination by acid mine drainage(AMD). Chemical and sulfur isotope compositions showed that spring water was affected by seepage from mine tailings, and seepage of stonewall, a part of treatment system, was affected by both seepage from mine tailings and mine adit drainage. Through the treatment system no appreciable decrease of sulfur content was identified. And almost similar sulfur isotope compositions of water from each stage of the treatment system may suggest incomplete or very poor sulfate reduction by sulfate reducing bacteria.
