Neutralizing Acid Mine Drainage
We paid an initial $10,000 to fight acid mine drainage from Cherry Creek into Deep Creek Lake. Cherry Creek is one of the major streams in the Deep Creek Watershed, and a major route for water flowing into Deep Creek Lake. The largest of the mines near Cherry Creek discharges an average of 60 gallons of acid mine drainage per minute.
The U.S. Department of the Interior and the State of Maryland have worked to neutralize the acid in the water with projects that include a limestone doser (originally paid for by the Spencer-Lang Foundation), that releases regulated amounts of acid-neutralizing limestone into the water. We are now adding our strength to these teams by paying for the limestone that goes into the doser.
