BRISTOL, Pa. (AP) – An environmental group is calling out a Pennsylvania regulator’s study that found radiation levels in oil and gas industry wastewater and byproducts showed little potential for radiation exposure.
The January study by the state Department of Environmental Protection began after questions arose about the radioactivity in the huge volumes of wastewater and solid waste coming out of the ground during the state’s natural gas drilling boom.
The Delaware Riverkeeper Network released a review last week on the study of technologically enhanced, naturally occurring radioactive materials that are brought to the surface by the shale gas drilling industry. It says the study used inaccurate radon measurements and sampling methods. It says the study also improperly tested stream water quality.
The state said it has received the review and declined to comment.
