Chemicals? Since when is water a chemical? That’s what they pump into the ground during a fracking operation. The water contains a small percentage of methanol and sand. Methanol is biodegradable. Groundwater aquifers are seldom any deeper than 500 feet. Fracking operations occur at 3,000 to 6,000 feet or deeper.
Though, I have heard an interesting (and more believable than the others) hypothesis on the connection between fracking and the small earth tremors that are occurring in areas where there is a lot of fracking happening. This came from an oil company engineer no less. He thought that the fracking was forcing the sand and water deposits in between opposing faults, making it easier for the faults to slip against each other, thereby causing the tremors.
Water is one of the best chemical solvents on God's green earth. But I digress.
Most of the fracking fluids being used have proprietary chemical compositions. Some have included benzene, a carcinogen. Various levels of gubmint are trying to demand disclosure of fracking fluid ingredients.
Corrections are always appreciated.
Which would be a good thing. Rather than letting the forces build up to a major quake. They should be thanking the frackers.
Don’t you realize how DANGEROUS Dihydrogen Monoxide is?
