Director: Tracy Branam
Other Researchers: John B. Comer
Funding: Indiana Department of Natural Resources (DNR) - Division of Reclamation (DOR)
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 runoff from seeps that develop at abandoned mine land sites after reclamation.
Approach: We collected and analyzed water from selected seeps and evaluated each seep for application of anoxic limestone drain abatement technology.
Products: When the project was completed, the chemical analyses and quality assurance and quality control (QA/QC) was furnished to the Indiana Department of Natural Resources in a final report.
Benefits: These analyses will enhance coal-mine reclamation projects that improve the quality of water flowing from abandoned mines.
