Hydraulic fracking is vertical well bores are drilled thousands of feet into the earth, through sediment layers, the water table, and shale rock formations in order to reach the oil and gas. The drilling is then angled horizontally, where a cement casing is installed and will serve as a conduit for the massive volume of water, fracking fluid, chemicals and sand needed to fracture the rock and shale. In some cases, prior to the injection of fluids, small explosives are used to open up the bedrock. The fractures allow the gas and oil to be removed from the formerly impervious rock formations. Although fracking has technically been in existence for decades, the scale and type of drilling now taking place, deep fracking, is a new form of drilling …show more content…

“Some of the pollutants released by drilling are benzene, toluene, xylene and ethyl benzene (BTEX), particulate matter and dust, ground level ozone, or smog, nitrogen oxides, carbon monoxide, formaldehyde and metals contained in diesel fuel combustion—with exposure to these pollutants known to cause short-term illness, cancer, organ damage, nervous system disorders and birth defects or even death.” There is a 2007 report prepared for the Western Governor's Association, that inventoried present and future nitrogen oxide and sulfur dioxide emissions from oil and gas drilling in the west, projects Montana to experience a 310% increase in smog. On top of all this there ARE NO regulations on fracking because of the Halliburton …show more content…

Not until recently, neither the federal nor state governments required drilling companies to disclose the ingredients used in frack fluids. Some states have begun to require that companies disclose the chemicals they use, but even some companies can withhold some chemical names under trade secret exemptions. As a result, a comprehensive list of chemicals used in the fracking process does not exist. Some states have begun to require that companies disclose the chemicals they use, but yet again confidential business information claims result in only partial disclosures. Corporations involved in fracking, like ExxonMobil have inserted loopholes in drilling legislation that allow them to keep various chemicals used in the fracking process secret. But just 2% of the billions of gallons of frack fluid created by gas drillers measures up to the use of hundreds of tons of toxic chemicals. “A 2011 report to Congress estimated that from 2005 to 2009, 14 leading fracking companies used (before mixing with water) 780 million gallons of 750 different chemicals”
