Abstract
The Pennsylvania Department of Environmental Resources and the Bureau of Mines are conducting a reclamation project aimed at controlling acid production at its source by surface application of high-quality limestone. The site of this project is a backfilled strip mine that discharges acidic water at three seepage areas. The site was reclaimed in May and June 1984 using 327 metric tons per hectare of high-quality limestone. The effect of the reclamation on water quality is currently being assessed in the last phase of the project. One year after reclamation, there has been no major improvement in the water quality in the wells and seeps. A sharp decrease in sulfate and acidity levels in two of the seeps occurred in late 1984; however, the improvement did not persist.
