PADOT Hits Paydirt?

From the Pittsburgh Post-Gazette: "Bags hold down sections of tarpaulin that keep rainwater from a hillside along Interstate 99 construction near State College. The road project has uncovered rock containing pyrite, which becomes highly acidic when exposed to oxygen and water. Acid runoff leaches into groundwater and streams, creating hazards."

Oops! I wonder whether Bauxsol can save the day!?
