Recently, here’s been a lot of public exposure to shale gas and hydro-fracturing (Fracking). The debate centers around the environmental impact and possible contamination of freshwater aquifers. Fracking can have a huge impact on the local water infrastructure as 3 to 5 million gallons of water are used per frack. This presents considerable implications especially for water short states such as California, where fracking is is now being considered.
Penn State University has constructed a clear and very informative infographic covering many of the questions the public may have about fracking (via Agile Geoscience). Check it out.
