Marcellus well cuttings contain all of the trace elements present in other Marcellus waste, including naturally occurring radioactive material (NORM) and pyrite (FeS2).The NY DEC has determined that Marcellus drill cuttings show radiation levels similar to other natural sources in the environment (e.g., dark shales that outcrop at the surface) and therefore likely do not pose a danger of radiation exposure to either workers or the general public. (For more information on NORM, please see Marcellus Shale Issue 4: Understanding Naturally Occurring Radioactive Material in the Marcellus Shale.)
