New Study Predicts Frack Fluids Can Migrate to Aquifers Within Years - ProPublica
"concluding that fracking chemicals injected into the ground could migrate toward drinking water supplies far more quickly than experts have previously predicted."
"But the study, using computer modeling, concluded that natural faults and fractures in the Marcellus, exacerbated by the effects of fracking itself, could allow chemicals to reach the surface in as little as "just a few years."
"The study in Ground Water is the first peer-reviewed research evaluating this possibility."
"fracking will dramatically speed up the movement of chemicals injected into the ground."
"As a result, chemicals left underground are still being pushed away from the drill site long after drilling is finished. It can take five or six years before the natural balance of pressure in the underground system is fully restored, the study found."

"According to Theo Colborn, approximately 37% of the chemicals used in the extraction and refining of natural gas
can volatilize. 89% of these chemicals can harm the eyes, skin, sensory organs, respiratory tract and gastrointestinal tract. Additionally, 81% of these volatile chemicals can damage the brain and/or nervous system. Volatile chemicals tend to have a greater effect on human health because they can become inhaled, ingested, or absorbed through the skin. Three groups of volatile compounds that have adverse effects on human health include ozone, hydrogen sulfide, and BTEX"
"According to the Oil and Gas Accountability Project (OGAP), drilling fluids that return to the surface “may contain dissolved and suspended contaminants including cadmium, arsenic, and metals such as mercury, copper and lead; hydrocarbons; hydrogen sulfide and natural gas, as well as drilling mud additives, many of which contain potentially harmful chemicals (e.g., chromate, barite)”

"649 different chemicals, more than half of which are known to disrupt the endocrine system. Exposure to these types of chemicals has been linked to certain cancers, diabetes, obesity, and metabolic syndrome (the name for a group of risk factors that occur together and increase the risk for heart disease, stroke, and type 2 diabetes). Fifty-five percent of the chemicals cause brain and nervous system damage, and many are linked to cancer and organ damage. The threat of exposure to these chemicals occurs via contaminated air, water, and soil."
"A 2010 study out of the University of Buffalo found that natural gas drilling using the fracking method could potentially contaminate water supplies with uranium."
Marcellus Shale Fracking Wastewater Harmful
"A new paper by Natural Resources Defense Council says hydraulic fracturing (fracking) generates massive amounts of polluted wastewater in in the Marcellus Shale that threatens the health of drinking water supplies, rivers, streams, and groundwater - and that federal and state regulations have not kept pace with the dramatic growth of fracking and must be strengthened to reduce the risks of health issues throughout the Marcellus region."
