A proposed pipeline, called Keystone XL, would carry oil from tar sands-a source of petroleum that is expensive, difficult, and environmentally damaging to extract- from Alberta, Canada, all the way to refineries on the Gulf of Mexico, in part for export to other countries. The pipeline would threaten local water sources all along its length, especially in the Great Plains, where it would travel across one of our nation's most important agui-fers. Elizabeth Shope, an associate advocate in NRDC's Washington, D.C., office who is working full-time to limit industrial development of tar sands, explains just how dangerous this pipeline would be.
