Environmental
groups finally have what they have been hoping for ever since natural gas
drilling began, evidence that fracking is harmful to the environment. Fracking
is a technique that uses highly pressured liquid (water and other chemicals) to
hydraulically fracture shale formations, creating veins that allow for the collection
of vast reservoirs of natural gas. Many areas that are “fracked” soon see
contaminates show up in their water resources. In Wyoming people started to see
particulates in their tap water that gave the water a brown hue. Environmental
researchers working with the EPA were able to link this to hydraulic fracking
nearby. While this is the first proven case of contamination, many people
across the country have reported contaminated water soon after natural gas
wells were built near their homes. In a small town in Pennsylvania methane
leakage was so bad that tap water turned flammable. Local residents were able
to hold a lighter to their faucets and see their water spark. This is because
of the many chemicals that are shot down wells to fracture shale. Substances
such as methane and lead are sent down right below underground aquifers. Ever
though there is a considerable distance between the bottom of the well and the
fresh water, some of the chemicals are still able to reach the underground
drinking water. Many chemicals that are used are classified as carcinogens and
can be detrimental to the health of anyone that is unfortunate enough to come
in contact with them. Methods and technologies that are associated with this
dangerous drilling technique must be cleaned up, or abolished. There are too
many people put at risk to justify drilling for natural gas. By improving
drilling technology we may someday be able to harvest the Earth’s natural gas
resources safely, but until then something must be done so that innocent people
are not forced to suffer and the surrounding areas are not destroyed.
