Fracking Chemicals

Lenin nightingale RINF Alternative News

US Congress legislation in 2005 exempted fracking companies from the regulatory supervision of the Environmental Protection Agency (EPA) under its the Safe Drinking Water Act. No other industry in is allowed to inject known hazardous materials near underground drinking water supplies. During Dick Cheney’s term as vice president he lobbied the EPA to give a thumbs up to a major expansion of shale gas drilling. His former company, Halliburton, is a major producer of chemical fracking fluids. In 2004, the EPA issued a study of the environmental effects of fracking. Following a whistleblowers sceptism of this study, the Oil and Gas Accountability Project conducted a review which found that EPA removed information from earlier drafts suggesting ‘fracturing fluids may pose a threat to drinking water long after drilling operations are completed’.

The Obama Administration and the Energy Department formed an advisory commission on fracking, headed by former CIA director John Deuss, a board member of both Citigroup (a bank that funds fracking companies) and Halliburton. Of the seven commission members, six had ties to the energy industry. Their report in 2011, not unsurprisingly, called shale gas, ‘the best piece of news about energy in the last 50 years’.

Shale needs to be fracked using a mixture of hot water, sand, and poisonous chemicals, the composition of which fracking companies claim to be proprietary secrets, and disclosing them would make them less competitive. However, scientists who have analyzed fracking fluid discovered the following substances common to diesel fuel: Benzene, Ethylbenzene, Toluene, Xylene, Naphthalene, Methanol, Formaldehyde, Ethylene glycol, Glycol ethers, Hydrochloric acid, Sodium hydroxide. Most fracking companies surveyed by a 2010 Congressional Committee admitted that diesel fuel is part of their fracking mixture. Where diesel fuel was not used, chemical mixtures includes high levels of benzene, a tiny amount of which can poison millions of gallons of water.

Theo Colburn, PhD, director of the Endocrine Disruption Exchange, Colorado, identified 65 chemicals that are probably used in fracking fluids. These included benzene, glycol-ethers, toluene, and ethanol, all of which have been linked to health problems when human exposure is too high. In 2012, ShaleTest visited many fracking sites in North Texas, monitoring ambient air using stainless steel summa canisters. Results showed the presence of the known carcinogen benzene. “It is unacceptable that the natural gas industries are ignoring the devastating impacts they have on citizens and the environment”, commented Susan Sullivan, board member of ShaleTest.

Fracking Chemicals Interfere With Hormone Function, Contaminate Groundwater With Endocrine-Disrupters

Medical Daily

Long suspected, the energy industry’s controversial practice of “fracking” may pollute ground water with chemicals disrupting the body’s hormones.

An investigator from the University of Missouri says energy companies use many endocrine-disrupting chemicals, known as EDCs, when extracting natural gas and other materials from the ground, contaminating the water. Today, EDCs may be found not only in groundwater but in manufactured products, foods, air, and soil — with well-documented links to infertility, cancer, and birth defects, says investigator Susan C. Nagel.

"More than 700 chemicals are used in the fracking process, and many of them disturb hormone function," Nagel, also a research scientist, said in a statement Monday. "With fracking on the rise, populations may face greater health risks from increased endocrine-disrupting chemical exposure."

In a study published Monday, Nagel and her colleagues examined a dozen suspected or known ECDs used by natural gas producers, measuring their effect on the body’s male and female reproductive hormones. The researchers took surface and groundwater samples from drilling sites in Garfield County, Colo., which has some 10,000 active natural gas wells as well as Boone County, Mo.
