Environmental impact of fracking in the United States has been an issue of public concern, and includes the contamination of ground and surface water, methane emissions, [1] air pollution, migration of gases and fracking chemicals and radionuclides to the surface, the potential mishandling of solid waste, drill cuttings, increased seismicity and associated effects on human and ecosystem health.
Fracking fluids include proppants and other substances, which include chemicals known to be toxic, as well as unknown chemicals that may be toxic. [5] In the United States, such additives may be treated as trade secrets by companies who use them. Lack of knowledge about specific chemicals has complicated efforts to develop risk management ...
In the US, about 750 compounds have been listed as additives for hydraulic fracturing, also known as ingredients of pressurized fracking fluid, [9] in an industry report to the US Congress in 2011 [10] [11] The following is a partial list of the chemical constituents in additives that are used or may have been used in fracturing operations. [12]
Increased seismic activity in North America and Europe near corridors of hydraulic fracturing has had some worried about the dangers that fracking could be causing. Arkansas even went as far as ...

Donald Trump's energy agenda targets fracking expansion, faster permits and US dominance, sparking debate over economic gains and environmental risks.
The forced change in geologic structure allows gas molecules to escape, therefore allowing the natural gas to be harvested. Hydraulic fracturing has changed the energy scene as a result of many technological advances. Fracking uses both historically-known vertical and horizontal drilling techniques which are used in tandem to extract oil and ...
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 ...
