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 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 ...
In the past, when companies were using conventional oil and gas drilling — a practice that poses equivalent risk of localized pollution to land or water supplies to fracking but uses much less ...
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 ...
The EIA credits horizontal drilling and hydraulic fracturing, or fracking – which uses water, sand and chemicals to pump oil from deep underground – with allowing producers to use fewer wells ...
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.
A period of increasing seismic activity in southeastern New Mexico in 2021, thought to be caused by the drilling and use of injection wells for disposal of wastewater, came with a regulatory ...
