Here are the some of the chemicals used in fracking. Some pretty bad stuff
FRACKING CHEMICALS
Chemicals used in fracturingWater is by far the largest component of fracking fluids. The initial drilling operation may consume from 65,000 gallons to 600,000 gal. Over its lifetime an average well will require an additional 5 million gallons of water for the initial fracking operation and restimulation frac jobs.
Chemical additives used in fracturing fluids typically make up less than 2% by weight of the total fluid. They are biocides, surfactants, adjusting viscosity, and emulsifiers. Many are used in household products such as cosmetics, lotions, soaps, detergents, furniture polishes, floor waxes, and paints.[37] Some are also used in food products. A list of the chemicals that have been used was published in a U.S. House of Representatives Report.[27] Some of the chemicals pose no known health hazards, some others are known carcinogens, some are toxic, some are neurotoxins. For example: benzene (causes cancer, bone marrow failure), lead (damages the nervous sytem and causes brain disorders), ethylene glycol (antifreeze, causes death), methanol (highly toxic), boric acid (kidney damage, death), 2-butoxyethanol (causes hemolysis). The report does not include the concentration of each chemical used or the amount used.
A 2011 study identified 632 chemicals used in natural gas operations. Only 353 of these are well-described in the scientific literature; and of these, more than 75% could affect skin, eyes, respiratory and gastrointestinal systems; roughly 40-50% could affect the brain and nervous, immune and cardiovascular systems and the kidneys; 37% could affect the endocrine system; and 25% were carcinogens or mutagens. The study indicated possible long-term health effects that might not appear immediately. The study recommended full disclosure of all products used, along with extensive air and water monitoring near natural gas operations; it also recommended that fracking's exemption from regulation under the US Safe Drinking Water Act be rescinded.
