Living on Earth: Disposal of Fracking Wastewater Polluting PA Rivers
FRAZIER: Each Marcellus shale gas well produces millions of gallons of salty water. The water is full of bromides, and until recently, drillers in Western Pennsylvania trucked this brine to wastewater plants for disposal. The plants could treat the water for metals and other pollutants, but not bromides. That requires expensive new technology. The plants would simply release the treated water--bromides and all--into rivers and streams.
