"EPA Launches National Study of Hydraulic Fracturing"

"Responding to reports of environmental contamination in gas drilling areas across the country, the U.S. Environmental Protection Agency will conduct a nationwide scientific study to determine if the problems are caused by the practice of injecting chemicals and water underground to fracture the gas-bearing rock.

The study, announced Thursday but hinted at for months, will revisit research the agency published in 2004, which concluded that the process of hydraulic fracturing did not pose a threat to drinking water. The 2004 report has been widely criticized, in part because the agency didn't conduct any water tests in reaching that conclusion."
