Case story

Construction on I-99

USA, Pennsylvania

Many states are faced with the problem of dealing with tailings and residues from mining, road building, and other sources that pose a threat to groundwater. Residues can come from both old inventories of stockpiled material, as well as those materials recently excavated in order to provide roads and access to mining areas.

The leachate from these tailings produces an iron oxide material that can, if not monitored and controlled, flow into drinking water, streams, and rivers.
