Nearby Zn-Pb deposits hosted in associated sandstone and limestone in Blair and Centre Counties were prospected in the past; however, these deposits generally were not viable as commercial mines. The pyritic sandstone from the roadcut was crushed and used locally as road base and fill for adjoining segments of I-99. Within months, acidic (pH1,000 mg\/L), seep waters at the base of the cut contain \u0026gt;100 mg\/L dissolved Zn and \u0026gt;1 mg\/L As, Co, Cu, and Ni.
