According to the New York State Department of Environmental Conservation, fracturing fluids typically contain about 90 percent water, about 9 percent propping agents like silica sand and less than 0.5 percent chemicals.

When experts spew out statements like this, hiding absolute numbers behind safe-sounding percentages, when they deliberately obfuscate the word "chemicals" to make a political point, and when "journalists" cannot be bothered to research what the "less than 0.5 percent chemicals" contains, my heart trembles for any hope of an enlightened citizenry.

But all that sounds like fearful piffling on my part, and even responding to it makes me sound like a liberal loser wonky type.

Heck, air is mostly nitrogen, with a small chunk of oxygen tossed in. I wonder if the committee that spewed this nonsense would mind sitting in a room with only 0.5% carbon monoxide during one of its meetings.

No, that was not a threat. Allowing fracking near someone's water supply, however, is a threat.
We're letting them frack with our water--what would Thomas Jefferson do?
