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.
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.
The COGCC reports that 26,385 gallons of such water has leaked into flood waters. [56] Over 50,000 fracking wells – a mining process utilized in the extraction of oil form the Earth – operate in the state of Colorado and 1,900 fracking wells were flooded at the peak flood levels. This number has since been reduced to around 1,300 wells.

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]
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 ...
