Water

Unconventional oil and gas development requires extraordinary amounts of water during the extraction process. In 2019, fracking operators used an average of 14 million gallons of water per well, with the maximum amount reaching 39 million gallons for a single well. After being pumped underground to “frack” oil and gas wells, water is called “flowback,” and includes naturally occurring underground brine water– which contains dangerous levels of radiation, heavy metals, and other contaminants — mixed with the fracking chemical-laden fresh water that has been pumped into the well. The chemicals used in the fracking process are known carcinogens, while others remain entirely secret, even to the personnel in the field who are employed to use the additives. 

Flowback is disposed of by injection into underground wells, in water treatment plants, or in open air pits. Each of these disposal methods comes with enormous risks, such as contamination of drinking water sources, fresh water contamination, inducing seismic activity in the case of underground injection, human exposure to radioactivity, and increased traffic needed to transport produced water. Sometimes produced water is treated to remove some of the fracking chemicals and reused in the fracking process, but this accounts for only a portion of fracking water given that fresh water is cheaper to procure.

Shockingly, some states allow for fracking wastewater to be treated and used for agricultural purposes, for road spreading, or for commercial sale in products such as pool salts, increasing exposure pathways to toxic chemicals.
