Researchers make massive lithium discovery in Pennsylvania

Scientists from the University of Pittsburgh have discovered a large amount of lithium located in Pennsylvania, saying it could eventually supply more than a third of America’s needs for the mineral.

Researcher and study lead author Justin Mackey told CBS Pittsburgh in an article published Wednesday that the wastewaters of the Marcellus Shale gas wells could cover “somewhere between 30 and 40 percent of the current U.S. national demand.”
