How much water is used during the fracking process? Generally 1-8 million gallons of water may be used to frack a well. A well may be fracked up to 18 times. What fluids are used in the fracking process? For each frack, 80-300 tons of chemicals may be used. Presently, the natural gas industry does not have to disclose the chemicals used, but scientists have identified volatile organic compounds (VOCs) such as benzene, toluene, ethylbenzene and xylene. In what form does the natural gas come out of the well? The gas comes up wet in produced water and has to be separated from the wastewater on the surface. Only 30-50% of the water is typically recovered from a well. This wastewater can be highly toxic. What is done with the wastewater? Evaporators evaporate off VOCs and condensate tanks steam off VOCs, 24 hours a day, seven days a week. The wastewater is then trucked to water treatment facilities. What is a well's potential to cause air pollution? As the VOCs are evaporated a
