A lesson on Fracking
Today let’s talk about fracking. It’s a subject that is constantly in the news. However, what is fracking? Well, fracking or hydraulic fracturing is the process of drilling and injecting fluid into the ground at a high pressure in order to fracture shale rocks to release the natural gas inside.
The process involves using a lot of water that at the fracking site is mixed with up to 600 different chemicals; including lead, uranium, and mercury. The fracking fluid is then pressure injected into the ground through a drilled pipe. When this mixture reaches the end of the well it causes the nearby shale rock to crack, creating fissures where natural gas flows into the well.
