The Hazards of Fracking

Improvements in the extraction of natural resources using a technique called fracking or hydraulic fracturing has led to higher gas and oil production in the United States over the past decades. Concerns regarding negative environmental impacts and potential violations of the Safe Drinking Water Act associated with fracking make the process controversial. Fracking works by forcing fluids into a well and fracturing rock deep underground. Chemicals are added to prevent the rock channels created from closing once pressure of the fracking fluids are reduced. These channels provide conduits for fluids or gases to flow from the well thereby increasing its yield. This informative two minute video describes the process and hazards of fracking.
