What are the advantages and disadvantages of fracking? What will be an ideal response?
Fracking, in concert with improvements in horizontal drilling technology, is a significant energy
production innovation.
Its use has large costs to the public, as it is clear that it produces toxic, and sometimes radioactive,
wastewater that has the potential to contaminate surface water and water wells. For example, in 2011,
after a 3-year study, the EPA confirmed the presence of toxic chemicals often associated with fracking
in contaminated well water in Pavillion, Wyoming, an area that is home to nearly 170 natural gas
wells.
