Is There Fracking in Our Future?

Nine states in the Northeast and the Rocky Mountains have enacted guidelines to regulate hydraulic fracturing, or "fracking," a process involving injection of chemicals into the ground to extract natural gas. In California, it's being used on thousands of oil wells, but oil companies won't reveal what the chemicals are. A company called PXP wants to use fracking in the Inglewood/Baldwin Hills Oil Field. In Sacramento, oil companies are opposing a bill that would require them to report where fracking is going on, for how long, with how much water, and with what chemicals.
