What the Frack?

You may have heard about it on the news recently: Fracking. The long term for it is Hydraulic Fracturing. Its a process by which millions of gallons of chemicals and water are pumped deep into gas-containing shale rock to fracture it and let the gas seep to the surface for collection. Its the biggest boon to the Natural Gas industry in decades, and is helping to drive down energy prices across the USA, which happens to be one of the largest sources of natural gas energy in the world. Heres a neat diagram showing how fracking works

On the surface, the process seems innovative and safe, but deep below the ground the chemicals, such as Methanol, are seeping into water tables and contaminating important aquifers in the northeast and Rocky Mountain west states, where the largest reserves of natural gas lie. Many gas companies claim the water stays deep underground, but natural capillary forces move the chemicals and contaminated water upward into looser surface layers where aquifers lie. Such chemicals are often highly poisonous and toxic to both the environment and to us Humans. These normally shouldn't be used in these instances, but thanks to a loophole in an energy bill passed by the Bush Administration and hurried through congress by Dick Cheney and Halliburton, these chemicals are not monitored by the E.P.A. and thus can be used without regulation, polluting the environment without any liability to the natural gas companies.

To make matters worse, since the recession hit 3 years ago, gas companies have been baiting landowners with high-paying contracts to use their land for fracking. A one-time installation of a fracking well can pay off in a short amount of time to the company while leaving the landowner with slowly degrading well water and hazardous chemicals. In the popular documentary Gasland, one homeowner in Pennsylvania is able to light his faucet tap water on fire simply due to the high concentration of gas and methanol seeping into his wellwater. Its disgusting, and people don't yet know how hazardous fracking really is. We urgently need to spread awareness of this problem and combat this situation before it gets out of hand and we're left with poisoned citizens and degraded watersheds across the U.S., simply because we wanted cheap gas.
