In this Sept. 1, 2010, photo, workers drill wells as part of a project to clean up the groundwater at the site of a blowout at a natural gas well in northeast Wyoming's Line Creek Valley. The blowout in 2006 created a plume of pollution, including benzene, that has residents worried about the long-term safety of their drinking water. (AP Photo/Mead Gruver)
