"CHARLESTON, W.Va. -- A state-sponsored study meant to examine potential pollution from the boom in natural gas drilling never actually tested key wastes from the Marcellus Shale formation, according to a West Virginia University researcher who led the effort."
"Teams performing the legislatively mandated review examined only materials from the vertical portion of wells, not from the horizontal drilling at those same sites, which would have included Marcellus Shale mud and drill cuttings.
The omission is important because researchers believe material from the Marcellus Shale is generally more radioactive, and citizen groups are expressing growing concern about the risks of handling and disposal of radioactive drilling wastes."
