The barging industry has the answer. It’s nowhere near as complicated as it seems. As shale gas production continues to ramp up across the United States, millions of gallons of wastewater is created through the process of hydraulic fracturing, or fracking. That waste, referred to as shale gas extraction wastewater (SGEWW), or frack water, needs transport to storage and reprocessing facilities around the U.S., including disposal sites in Louisiana, Texas and Ohio. At the moment, the cargo is carried solely by rail and truck.
