Water and air pollution are the biggest risks to human health from fracking. [1] Research has determined that fracking negatively affects human health and drives climate change. [2] [3] [4] Fracking fluids include proppants and other substances, which include chemicals known to be toxic, as well as unknown chemicals that may be toxic. [5]
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.
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 ...
Chemicals used for fracking may travel through cracks in the rock into an underground drinking water source and contamination could also occur if a well is improperly installed, if chemicals are ...
While natural gas is often touted for its lower carbon emissions compared to coal, the environmental impacts of fracking—such as potential water contamination, air pollution, and contribution to ...
The governor announced the plan to tap the state's massive brackish water and fracking wastewater potential at the United Nations climate summit in Dubai in December, saying she would request $500 ...
Once the injection process is complete and gas has entered the well, anywhere between 10 and 30 percent of the fluid injected will flow back into the well as wastewater for disposal. In addition to the chemical additives present in fracking fluid, flowback water contains dangerous volatile hydrocarbons, such as H 2 S pulled from the fractured ...
The EPA responded with a study of potential and actual impacts of hydraulic fracturing of coalbed methane wells on drinking water, published in 2004. Section 7.4 of the report "concluded that the injection of hydraulic fracturing fluids into coalbed methane wells poses little or no threat to USDWs and does not justify additional study at this ...
