.5% of 10000 gallons of injected hydraulic fracking fluid is 50 gallons of additives. Which of these additives "are already there and have been there for Millions of years?" Which ones would you allow a corporation to pour into your favorite fishing hole with the guarantee that "They also get every square ounce of those “toxic” chemicals back to the surface?"
I'm all for drilling and becoming energy independent with an "all-of-the-above" approach, but the long-term impacts also need to be considered.
Every chemical you listed except for Citric Acid is found in Oil. They separate the sulfur, chlorides, chemicals and water at the refinery level. They then distribute these “toxic” chemicals for industrial use and reuse.
And, as far as spilling them into your “fishing hole”, they have 3 different protective and tightly sealed well casing levels that insure against the production fluids ever leaking into the ground water at upper levels or at the surface.
It is also a fact that all the Frack Fluids are recovered and separated for recovery when the oil and those fluids are allowed to flow to the surface.
If you cannot understand this simple process in the means that I have described to you, from someone who is a Petroleum Drilling engineer and Consultant for over 30 years, then you are not only ignorant, you are an ass.
