Perspectives Who Bears the Burden of Fracking?
The amount of fracking going on in the US and around the world is huge, and the risks are mounting. The EPA report says:

We estimate 25,000–30,000 new wells were drilled and hydraulically fractured annually in the United States between 2011 and 2014. The report goes on to conclude that: Of the potential mechanisms identified in this report, we found specific instances where one or more mechanisms led to impacts on drinking water resources, including contamination of drinking water wells. The number of identified cases, however, was small compared to the number of hydraulically fractured wells.

A recent EPA report revealed that there remains significant uncertainty about the impacts of fracking.
T
he U.S. Environmental Protection Agency (EPA) released a report in June 2015 about the environmental impacts of hydraulic fracturing (fracking) on water resources.1 Fracking is a technique to extract oil and gas from shale deposits. While the report appeared to give the industry a clean bill of health as far as water quality is concerned—the report found “no evidence that fracking led to widespread, systematic pollution of water”—there are enough uncertainties in the data and its interpretation to raise concerns, many of which relate to specific, local pollution, as
well as other impacts. The report’s ambiguous conclusions have been seized upon by both sides of the debate, due to the huge remaining uncertainties. While the report seems to vindicate fracking as basically safe, it can also be interpreted as confirming specific cases of impacts and a call for more research and better oversight. Just because no evidence was found of widespread pollution, does not mean that no evidence will ever be found. In addition, even if fracking does not lead to widespread pollution, it can and has led to specific, local pollution.
So, of the 100,000 to 120,000 new wells drilled in the US since 2011, only a ‘small’ number led to the contamination of drinking water wells. For example, in terms of the frequency of spills of hydraulic fracturing fluids—only one of the several possible routes of contamination—it was estimated that: “the number of spills nationally could range from approximately 100 to 3,700 spills annually.” In addition, there is admittedly poor data on the impacts of fracking, so the ‘no evidence’ caveat is important. The EPA says: There is insufficient pre- and post-hydraulic fracturing data on the quality of drinking water resources. This inhibits a determination of the frequency of impacts. Other limiting factors include the presence of other causes of contamination,
