Alkarock: An Innovative Technology for Passive Treatment of Acid Mine Drainage
Researchers have tried for decades to use natural alkaline rock, like limestone and dolomite, to treat acid mine drainage. The primary obstacle has been the slow release of alkalinity and pH limitations. This project works to develop a man-made, rock-like material, using cement and other added alkali, to treat acid mine drainage and precipitate toxic metals in passive physical reactors. The goal is to produce a substance that can offer time-released, higher doses of alkalinity and return higher pH values. EPA, British Environment Agency, and the University of Greenwich (UK) participate in the project.
