This is an area of interest that needs further looking into. The article caught my eye when I saw "Halliburton" 'cause the name just sends shivers down my spine. Anyway, I would like to research this "fracturing" stuff a little more before I say much and insert foot in my mouth. But, while reading the piece, a little ways down they mentioned that these techniques are being used in the southeast part of the country. This is where my little antennae shot up.
Natural gas is currently being drilled largely in Arkansas, Missouri and Oklahoma. Fracturing is where they shoot very high pressure into long drill holes to help them find gas. I'm sorry, that's a lame explanation, but the best I can do right now. Ok, the "stuff" they shoot down there is totally unregulated. Doesn't that sound scary to anyone? I cannot, nor should I, be allowed to throw my household chemicals into my yard or into my septic. But the oil and gas industry can, and do.
My next epiphany was the "earthquakes" that have been happening in this tri-state area. I know that there is a fault line in Arkansas that is minorly active, but has increased activity over the last few years. Nothing major, like I said, but, You've got to stop and ask yourself, what the hell?
