It mostly depends on what is used in the hydraulic fracking fluids. Some of these "proprietary" mixes you wouldn't want spilled above ground near your favorite fishing hole, so they shouldn't be forced deep into the ground either, IMHO.

Conservatives laugh at the Greenies for sequestering CO2 that later carbonates ground water and causes other problems, so why would we allow something toxic forced into the ground to help extract gas/oil?

You are simply ignorant and have no understanding of the physics behind this process. Yet you are forming a very opinionated stance, based on that gross ignorance. Which is more than wrong.......

The Laws of Physics behind this process, guarantee that those “toxic” (Liberal terminology) chemicals you claim are injected into the ground, are already there and have been there for Millions of years. They simply use them because they are already compatible with the formation. They also get every square ounce of those “toxic” chemicals back to the surface because they blend with the Oil and gas that comes to the surface naturally, due to the Pressure gradient of the formation. Due to your gross lack of understanding, this is all the further I can explain this process to you. I would be glad to clear up any further misconceptions you most likely have, but you will have to let me know what those are.

I wouldn't want octane, butane or the other liquids already present in these formation in my fishing hole either. But they have nothing to do with each other. These formations are far below the water supply.

The last I checked gas/oil were toxic.
