This drilling technique is called hydraulic fracturing, or fracking. Generally, fracking generates huge volumes of wastewater known as “flowback” and “produced water.”. This fluid may contain the injected chemicals and naturally occurring materials such as brines, metals, radionuclides, and hydrocarbons. To dispose of the wastewater, some companies ...

frac fluid comes back up the well through the ‘flowback’ and dewatering processes. Once back to surface, the fluid flows to tanks or to lined storage dams. The flowback water is then tested for water quality and then disposed of by truck to an approved waste water facility or reused. Will hydraulic fracturing harm

Hydraulic fracturing in the United States, began in 1949. According to the Department of Energy (DOE), by 2013 at least two million oil and gas wells in the US had been hydraulically fractured, and that of new wells being drilled, up to 95% are hydraulically fractured.The output from these wells makes up 43% of the oil production and 67% of the natural gas production in the United States.
