Gas is the country’s second-largest domestic energy resource, after coal. It’s clean, cheap and abundant – estimates are there are half a million gas wells in 32 states already tapped into enough pockets of gas to power America at its 2008 rate of consumption for some 90 years. But there’s a catch. You can’t drink gas. The techniques used by powerful oil and gas companies to extract these fossil fuels from deep underground might be responsible for contaminating groundwater in drilling regions. The elephant in the well is the undisclosed chemical fluids used in hydro-fracturing. The industry hides behind federal protection, granted by the George W.

Major oil giants like Chesapeake or Shell or Chevron rely on service companies like Halliburton, BJ Services, and Schlumberger to do the actual drilling. Those companies, in turn, hire firms such as EnCana, Questar, and Devon to put the boots on the ground.
