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.
That explains your attitude.
