The Environmental Protection Agency (EPA) defines Hydraulic fracturing or “fracking” as a technique designed to recover gas from shale rock. Even though shale rock is a good source of natural gas, fracking this resource is a very controversial issue in the United States (EPA 2016). On one side of the issue, you have the gas companies who see the profitable benefits of fracking, while on the other side of the issue, you have environmentalists who are concerned with the construction techniques, fluids used and its long-term environmental impact, particularly to our water resources (EPA 2016).
