If EPA finds any contamination associated with the Norwood Landfill site that “exceeds” what is considered safe, will EPA clean up that contamination - even if the Agency cannot find any “pathways” for that contamination to reach humans or sensitive environments?

If the sampling data shows an exceedance of a screening level, EPA will consult with the site Toxicologist and the Agency for Toxic Substances and Disease Registry (ATSDR) to conduct a human health risk screening assessment to determine any potential threat to human health. EPA will also consult with the Biological and Technical Assistance Group for an ecological screening assessment to determine any potential impacts to sensitive environments.

At any time during the Superfund process, if the site is found to pose an immediate threat to public health or the environment, EPA can intervene with a removal action.
