Mining Wastewater

A new mine drainage treatment may be able to help clean wastewater.

Scientists from the U.S. Geological Survey say dried mine drainage sludge could be used as a low-cost absorbent to remove phosphorus from water.

Officials say the new technology can help lower mine drainage costs, prevent the degrading of aquatic ecosystems and recycle valuable nutrients.
