SUMMIT COUNTY — Nearly a century after miners finished digging millions of dollars worth of silver, lead and zinc out of the Pennsylvania Mine, heavy machinery will once again rumble through the high alpine Peru Creek Valley.
But instead of burrowing deep into the ground to find precious metals, the workers this time will be trying to clean up the big mess left behind when the mine was abandoned. For decades, water coursing through the mine shafts has been dissolving minerals, resulting in acid mine drainage that pollutes Peru Creek and the Snake River. Concentrations of some metals, especially zinc, are high enough to kill trout.
After years of studying the mine, experts with federal and state agencies now say they are ready to try and tackle the pollution. They will provide details on the cleanup plan at the May 29 meeting of the Snake River Watershed Task Force. The public meeting is scheduled from 2 p.m. to 4 p.m. at the Keystone Center, 1628 St. John Road, Keystone. (more…)
