Acid mine drainage reduces radioactivity in fracking waste

Blending fracking wastewater with acid mine drainage causes most of the naturally radioactive metals in the fracking water to precipitate into a solid for disposal. The practice also could help reduce the depletion of local freshwater resources by giving drillers a source of usable recycled water for the hydraulic fracturing process.
