Hydraulic fracturing — or fracking — is a process used by energy companies to get natural gas out of the ground. Fracking involves forcing water, sand and chemicals underground to fracture rocks and release the natural gas trapped within them.
But what happens to those chemicals once they’ve been injected into the ground? That depends upon whom you ask. In a joint effort with ProPublica, the non-profit investigative journalist organization, we sent correspondent John Larson to Wyoming, where some residents believe fracking is contaminating their water and risking their health.
Editor’s note: This video was temporarily taken off the site to reconfirm past and current energy industry affiliations of members of an EPA peer review panel. We determined that our original reporting and statements were accurate, but to avoid confusion about the members’ current affiliations, a graphic listing their names was removed with accompanying narration.
