The main issue with shale gas is the way it is drilled for and retrieved. A process called hydraulis fracturing is used, which “injects a mixture of water, sand and chemicals into rock formations to stimulate oil and natural gas production”. A SINGLE shale gas drilling operation on a site of many can require up to 4.5 million gallons of water, and that water, with all the chemicals and sand mixed in, has to be disposed of.
How do we dispose it? That’s the problem. There are few, if any, regulations regarding shale gas drilling, and there is a possibility that the solution used for hydraulic fracturing can contaminate drinking water and natural waterways.
