“Recovered fracking waste is left in open-air pits to evaporate. This releases volatile organic compounds, creating contaminated air, acid rain, and ground-level ozone. Metal ball bearings are added to fracking fluids to keep the fractures open indefinitely. These toxic chemicals leach out and contaminate nearby groundwater. Drinking-water wells near fracturing sites have been found to contain concentrations of methane seventeen times higher than normal.”
