Where Fracking Waste Spills, Concern for Groundwater

"The experiment is part of a research project at the USGS to determine the risk posed by fracking wastewater. The oil and gas industry produces billions of gallons of this waste every year. The waste is the briny liquid that comes out of a well after it’s been hydraulically fractured with millions of gallons of water.
