Gas in, gas out: the waterless fracking alternative
Drought raises appeal of using natural gas instead of water to fracture rock in wells
What Is Fracking?
„Fracking is short for hydraulic fracturing. It’s a method of extracting natural gas and oil from shale deposits deep within the earth. Water, chemicals, and sand are pumped into these shale deposits under very high pressure which causes the shale to fracture, releasing the natural gas and oil trapped within. The slurry of water, chemicals, gas, and oil are then slowly pumped back out, leaving the sand to hold the fractures open so the mixture can be removed. As the slurry of chemicals, water, sand, gas and oil is pumped back out of the ground, it is separated into its different components and stored in tanks.
And it’s the removal process where the problems lie for our groundwater. It’s been estimated that anywhere between 20 and 40 percent of the chemicals are left behind. They can then seep into the groundwater, contaminating wells and rendering the water undrinkable. „
„Benzene is one of the chemical components of the chemical cocktail pumped into the ground. It’s a byproduct of petroleum production and a Class A carcinogen. Benzene exposure has long been known to cause various forms of leukemia. Benzene exposure to eyes or skin can cause irritation. Drinking benzene in you water causes stomach irritation, vomiting, convulsions, rapid heartbeat and even death.“
