Hydraulic fracturing [a] is a well stimulation technique involving the fracturing of formations in bedrock by a pressurized liquid. The process involves the high-pressure injection of "fracking fluid" (primarily water, containing sand or other proppants suspended with the aid of thickening agents) into a wellbore to create cracks in the deep rock formations through which natural gas, petroleum ...
Hydraulic fracturing is the propagation of fractures in a rock layer by pressurized fluid. Induced hydraulic fracturing or hydrofracking, commonly known as fracking, is a technique used to release petroleum, natural gas (including shale gas, tight gas and coal seam gas), or other substances for extraction, particularly from unconventional reservoirs. [1]
The process involves the high-pressure injection of "fracking fluid" (primarily water, containing sand or other proppants suspended with the aid of thickening agents) into a wellbore to create cracks in the deep rock formations through which natural gas, petroleum, and brine will flow more freely.
According to the Department of Energy, fracking now accounts for 95% of new wells in the U.S., generating two-thirds of the total gas market and nearly half of the nation’s crude oil production.
The United States Geological Survey notes that fracking involves injecting water into bedrock to loosen it and retrieving oil and gas deposits. What is fracking? How the process works.

Exposure to fluids involved in fluid spills (flowback water, fracking fluid, produced waters) also exposes nearby workers to any and all compounds, toxic or not, contained within those fluids. [171] Between 2009 and 2014, more than 21,000 individual spills were reported across the U.S., involving a total of 175 million gallons of wastewater ...
Environmental officials in New Mexico took initial steps Monday toward regulating the treatment and reuse of oil industry fracking water as the state grapples with scarce water supplies and fossil ...
