After five years, the cleanup operations at the Foote Mineral federal Superfund site in East Whiteland, Pennsylvania is coming to a conclusion. Site crews have finished installing a 10-acre geosynthetic cap to seal off the old lithium tailings and other pollutants. Because of concerns with root penetration into the cap, trees and shrubs will be avoided. Instead, a 2MW solar farm is planned. A brownfield’s grant has already provided roughly $2.5 million towards the site reuse plan.
