BRIDGEPORT, W.Va. (AP) - A state environmental official says Marcellus shale drilling sludge dumped at a landfill in Harrison County has a low level of radiation.
Division of Water and Waste Management director Scott Mandirola says the sludge contains a fraction of a year's acceptable radiation exposure for workers.
Mandirola says Waste Management won't be cited for dumping the sludge at its Meadowfill landfill.
Another Waste Management landfill in Pennsylvania had rejected the sludge.
Mandirola says inspectors with the West Virginia Department of Environmental Protection checked the sludge at the Meadowfill landfill with radiation detectors. He says it measured 20 microrems per hour above natural radiation levels.
He says the federally acceptable exposure level for radiation workers is 5 rems per year, or 570 microrems per hour.
