Oil and water don’t mix, they say, but when it comes to drilling an oil and gas well, water is a big part of the process.
Each day, 2.4 billion gallons of wastewater pour out of U.S. oil and gas wells according to 2009 estimates from Argonne National Lab. This includes water pumped down for fracking and water that flows up to the surface from deep aquifers. Both contain dissolved minerals and chemicals including many that are harmful, and both can have impacts on drinking water resources if not handled with care, according to a 2015 report from the EPA.
