Environmental Protection Agency illustration of the water cycle of hydraulic fracturing. Fracking in the United States began in 1949. [1] 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.
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 ...
Water usage by fracking can be a problem in areas that experience water shortage. Surface water may be contaminated through spillage and improperly built and maintained waste pits, in jurisdictions where these are permitted. [9] Further, ground water can be contaminated if fracturing fluids and formation fluids are able to escape during ...
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.

Donald Trump's energy agenda targets fracking expansion, faster permits and US dominance, sparking debate over economic gains and environmental risks.
Fracking According to available studies on its environmental relevance, the fracking technology in unconventional natural gas production – particularly in shale gas production – is a technology with enormous potential risks. The effects on humans, nature and the environment are scientifically not yet sufficiently clarified.
Geothermal energy is clean and green, but it's also hard to find good sites for its development. Stealing a page from fracking's playbook could change all that, but does it sully geothermal's ...
