Fracking is the process of drilling down into the earth before a high-pressure water mixture is directed at the rock to release the gas inside. Water, sand and chemicals are injected into the rock at high pressure which allows the gas to flow out to the head of the well. Fracking can cause drinking water being dangerous to drink. There has been a lot of money spent on trying to keep fresh water at places where fracking is being used.
