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.
The increase in fracking from 2009 led to a drop in natural gas prices that made natural gas become more competitive with coal. This analysis estimates coal generation decreased as a result by 28%, which led to an average reduction of 4% in air pollution yielding positive health benefits.

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.
The June 2015 draft report of an ongoing EPA study on fracking effects on drinking water listed a number of mechanisms by which fracking can degrade drinking water. The draft report noted among its major findings: We did not find evidence that these mechanisms have led to widespread, systemic impacts on drinking water resources in the United ...
