Hydraulic fracturing: environmental issues

High volume hydraulic fracturing of deep shale deposits has transformed the oil and gas industry, catapulting the United States (U.S.) into the biggest oil and natural gas producer in the world, surpassing Russia as of June 2015. Hydraulic fracturing has been a game changer providing an
important measure of energy independence for the U.S. As one expert put it, "Shale deposits are a gift from God." Hydraulic fracturing operations in North Dakota, in the Marcellus formation in Pennsylvania, West Virginia, and Ohio, and in multiple other states are the subject of increased media,
public, and regulatory attention. New potential shale plays across the U.S. are also being examined, including the Monterey shale formation in California where hydraulic fracturing is a timely and significant environmental issue.

Concurrent with the increased development of unconventional hydrocarbon resources are concerns over perceived risks to the environment that have been raised at hydraulic fracturing locations throughout the U.S. These biogeochemical changes occurring in the millions of gallons of hydraulic fracturing
wastewater creates a unique dilemma for the disposal and potential reuse of these waters. Traditional disposal options are now less available due to public concern over safety risks, so water reuse is becoming the go-to solution, often requiring new treatment technologies to make the water suitable
for reuse in the hydraulic fracturing process. This book focuses on these issues fracking poses as well as the solutions to make it viable.
