Fatigue, burning eyes, skin irritation, headaches, upper respiratory problems. These are just a few of the health issues experienced by those living in the vicinity of fracking sites. Fracking, which is the slang for hydraulic fracturing, is a the process of drilling into deep tight-rock shale formations to unearth previously unavailable energy sources such as natural gas and oil. As the EEC Environmental company website explains: “The fracking process involves pumping water, chemicals and sand (proppant) slurry at high pressure into a well, which fractures the surrounding rock formation and props open passages, allowing natural gas to more freely flow from rock fractures to the production well” (Brief History n.pag). This process obtaining …show more content…
Oil and gas industry scientists contend that the risk for contamination is low. “The shale layers can be a mile or more deep, separated from shallow aquifers by thousands of feet of rock” (qtd. in Mooney, 2011). While this conclusion may appear true on the surface, it assumes that only one borehole is being drilled on a site, when in fact most sites are riddled with multiple boreholes of various depths. Mooney of Scientific American explains, “To maximize access to the gas, companies may drill a dozen or more vertical wells, closely spaced, at a single site” (2011). This fact alone results in the previous statement being misleading at best and down right lying at worst. “Imagine this Swiss cheese of boreholes going down thousands of feet -- we don’t know where they are” (qtd. in Mooney, 2011). Mazes of fractured ground such as these could release a number of contaminants into surrounding aquifers.
One such contaminant is methane, and while methane is a naturally occurring gas trapped within pockets of bedrock, the fracking process releases large amounts into surrounding groundwater supplies. Researchers in Pennsylvania found that the “average methane level was 17 times higher in private drinking wells within one kilometer, or about 3,280 feet, of active drilling sites, compared with those in non drilling areas” (McDermott-Levy et al, 45). Methane accumulations at these levels could lead to suffocation in the worst case scenario,
