fracking
- Fracturing a deep shale layer one time to release natural gas might pose little risk to drinking-water supplies, but doing so repeatedly could be problematic
- The U.S. is estimated to have 827 trillion cubic feet of this "unconventional" shale gas within reach—enough to last for decades—although industry e-mails published by the
- The EPA claimed that two residential drinking-water wells near two of the company’s gas wells were contaminated with methane of deep, "thermogenic" origin. That kind of gas originates in shale layers, unlike "biogenic" methane, which is produced by microbes in pockets closer to the surface, where aquifers typically are.
- The EPA also claimed that one of the wells contained chemicals sometimes used in fracking—such as benzene—and was delivering flammable water.
- New York Times in June suggest the resource may be more difficult and expensive to extract than companies have been claiming.
- water blasts deep underground can directly contaminate drinking water, by creating unexpected pathways for gas or liquid to travel between deep shale and shallow groundwater.
- The massive industrial endeavor demands a staggering two to four million gallons of water for a single lateral, as well as 15,000 to 60,000 gallons of chemicals.
- the depths of the gas and the combination of fracking and directional drilling, instead of 80,000 gallons of water it is now millions of gallons per fracking operation

Hydraulic fracturing, or “fracking”, is the process of drilling and injecting fluid into the ground at a high pressure in order to fracture shale rocks to release natural gas inside.
Each gas well requires an average of 400 tanker trucks to carry water and supplies to and from the site.
It takes 1-8 million gallons of water to complete each fracturing job.
The water brought in is mixed with sand and chemicals to create fracking fluid.
Approximately 40,000 gallons of chemicals are used per fracturing.
Up to 600 chemicals are used in fracking fluid, including known carcinogens and toxins such as… lead, uranium, mercury, ethylene glycol, radium, methanol, hydrochloric acid, formaldehyde
Down 10,000ft - The fracking fluid is then pressure injected into the ground through a drilled pipeline.
72 trillion gallons of wate and 360 billion gallons of chemicals needed to run our current gas wells.
The mixture reaches the end of the well where the high pressure causes the nearby shale rock to crack, creating fissures where natural gas flows into the well.
Contamination - During this process, methane gas and toxic chemicals leach out from the system and contaminate nearby groundwater. Methane concentrations are 17x higher in drinking-water wells near fracturing sites than in normal wells
Drinking Water - Contaminated well water is used for drinking water for nearby cities and towns.
There have been over 1,000 documented cases of water contamination next to areas of gas drilling as well as cases of sensory, respiratory, and neurological damage due to ingested contaminated water.
Left Behind - Only 30-50% of the fracturing fluid is recovered, the rest of the toxic fluid is left in the ground and is not biodegradable.
The waste fluid is left in open air pits to evaporate, releasing harmful VOC’s (volatile organic compounds) into the atmosphere, creating contaminated air, acid rain, and ground level ozone
In the end, hydraulic fracking produces approximately 300,000 barrels of natural gas a day, but at the price of numerous environmental, safety, and health hazards
So what?
