Gov. John Hickenlooper today dismissed the fears of activists and community members concerned that the natural gas drilling process of hydraulic fracturing can contaminate groundwater supplies, but he conceded the state should require the industry to disclose chemicals used in the “fracking” process. “Everyone in this room understands that hydraulic fracturing doesn’t connect to groundwater, that it’s almost inconceivable that groundwater will be contaminated,” Hickenlooper said in the opening speech of the Colorado Oil & Gas Association (COGA) annual meeting in Denver, according to the Denver Business Journal
