Green Risks: 2016

Though cumulatively, hydraulic ,fracturing, used on average 44 billion gal of water a year in 2011 and 2012, this represented less than 1% of total ,annual, water used in the United States. However, in areas of drought the need for a median of 1.5 million gallons to frack a well could impact water supplies.

Flowback, water. After a ,fracturing, treatment on a gas well, the pumping pressure is relieved and ,fracturing fluid,, mixed with water from the rock formation, begins to ,flow back, through the well casing to the wellhead. In treatment-and-reuse scenarios, this is the water that will serve as the basis for ,fracturing fluid, for the next job.
