Other Researchers: Peg Ennis, Ron Smith, John Comer
Issue: Major river systems in southwestern Indiana continue to be degraded by acid runoff from abandoned mine lands. Restoring these riverine ecosystems requires continuing evaluation and appropriate implementation of a variety of acid abatement strategies.
Objective: The purpose of this project was to abate acid mine drainage that forms at the Friar Tuck site and flows into the Wabash River drainage system.
Approach: We collected and analyzed bi-monthly the inflow and outflow from a constructed wetland to evaluate the effectiveness of this acid abatement strategy at the Friar Tuck abandoned coal mine site.
Products: A final report contained an evaluation of the effectiveness of the wetland treatment system in abating acid drainage.
Benefits: Improvements to existing coal-mine reclamation methods for improving the quality of water flowing from abandoned mines benefited the state of Indiana.
