FRACKING

Fracking is slang for hydraulic fracturing, and both terms describe the process used to frack (or frac) Marcellus Shale gas wells. To release methane from shale, high pressure is used to crack the shale formation. While there are alternatives to water for fracking gas wells (like liquid nitrogen gas) production companies prefer to use water since higher hydraulic pressures are created.

Federal health review calls compounds in Dimock water a concern

By Laura Legere / Harrisburg Bureau
Pittsburgh Post-Gazette

May 25, 2016 – In 27 water wells, the agency found that levels of arsenic, cadmium, copper, iron, lead, lithium, manganese, potassium or sodium were high enough to affect the health of adults, children or people with existing health problems. A man-made chemical, 4-chlorophenyl-phenyl ether, was also detected in two water wells.

In 17 water wells, the agency found that methane levels could create a hazard if the flammable gas builds up in poorly ventilated areas. Three of five wells with high enough methane concentrations to pose an immediate safety hazard did not have methane treatment systems in place as of January 2013, the agency reported.

  Reports indicate that hydraulic fracturing pressures can reach as high as 10,000 to 15,000 psi (pounds per square inch). Chemicals are added to the water and sand for the 'slick water' hydraulic fracturing commonly used on Marcellus wells. As more well laterals lengthened to two miles in 2015, it was estimated the average well required 2-million pounds of frac sand.

 

A New Poll Finds More Americans Oppose Fracking Than Support It

November 13, 2014 – A clear majority of Americans now oppose hydraulic fracturing, according to a new poll by the Pew Research Center. Development of the process over the last decade or so has led to a boom in North American fossil fuel production, but it’s also come along with a host of problems — studies suggest at least ten percent of the chemicals used in the fracturing fluid are toxic, posing a threat to drinking water; people who live near fracking wells are more likely to become sick thanks to the pollution; methane leaks from the industry exacerbate global warming; and the process may even trigger earthquakes. 

According to Pew, support for fracking stood at 48 percent in March of 2013, versus 38 percent opposition. But as of November 2014, Americans have flipped their position: 41 percent now favor the process while 47 percent oppose it.

New Study Predicts Frack Fluids Can Migrate to Aquifers Within Years

May 1, 2012 - Scientists have theorized that impermeable layers of rock would keep the fluid, which contains benzene and other dangerous chemicals, safely locked nearly a mile below water supplies. This view of the earth's underground geology is a cornerstone of the industry's argument that fracking poses minimal threats to the environment.

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." "Simply put, [the rock layers] are not impermeable," said the study's author, Tom Myers, an independent hydrogeologist whose clients include the federal government and environmental groups.

Story

Below is a collection of fracking photos which show the extensive arrays of fracking equipment that needs to be assembled on a Marcellus Shale drilling pad to frac a well. During fracking activities, truck traffic to a well site is extremely heavy with some locations recording as many as 100 truck trips per hour.

One well can require 50 to 60 tractor trailer loads of frac sand.

Most well pads have several wells.

Chemical descriptions: Multiple sources

TRADE NAME PURPOSE INGREDIENTS CHEMICAL ABSTRACT NUMBER (CAS #)
Acid, Hydrochloric 15% Acid Hydrochloric Acid 7647-01-0
   

Concentrated hydrochloric acid (fuming hydrochloric acid) forms acidic mists. Both the mist and the solution have a corrosive effect on human tissue, with the potential to damage respiratory organs, eyes, skin, and intestines.

WIC-641L Iron Control Agent Citric Acid 77-92-9
WAI-251LC Corrosion Inhibitor Ethylene Glycol 107-21-1
   

Ethylene glycol has been shown to be toxic to humans and is also toxic to domestic pets such as cats and dogs. Ethylene glycol is a toxic, colorless, odorless, almost nonvolatile liquid with a sweet taste and is occasionally consumed by children and dogs for its sweetness. Following ingestion the symptoms of poisoning follow a 3 step progression starting with intoxication and vomiting, before causing metabolic acidosis, cardiovascular dysfunction, and finally acute kidney failure.

    Dimethyl Formamide 68-12-2
   

Dimethylformamide (DMF) has been linked to cancer in humans, and it is thought to cause birth defects. In some sectors of industry women are banned from working with DMF.

    *Proprietary* *N/A*
    Decanol 112-30-1
   

Decanol causes a high irritability to skin and eyes, when splashed into the eyes it can cause permanent damage. Inhalation and ingestion can be harmful; it is harmful in the environment.

    Isopropanol (Isopropyl Alcohol, Propan-2-ol) 67-63-0
    Octanol 111-87-5
    2-Butoxyethanol (Ethylene Glycol Monobutyl Ether) 111-76-2
   

Moderate respiratory exposure to 2-butoxyethanol often results in irritation of mucous membranes of the eyes, nose and throat. Heavy exposure via respiratory, dermal or oral routes can lead to hypotension, metabolic acidosis, hemolysis, pulmonary edema and coma. Acute exposure to high levels of the glycol ethers in humans results in narcosis, pulmonary edema, and severe liver and kidney damage. Chronic exposure to the glycol ethers in humans results in fatigue, lethargy, nausea, anorexia, tremor, and anemia. 2-Butoxyethanol has come under scrutiny in Canada.
