After choosing a benchmark established by the Nuclear Regulatory Commission (NRC) that wasn’t meant to assess risk to human health from radioactivity in landfill leachate, the agency came to bold conclusions. https://scoop.publicherald.org/p/state-investigation-finds-all-pennsylvania?r=b7r7s&triedRedirect=true
In this case, DEP discretion manufactured what it considered safe, not necessarily establishing, by way of public input or congressional approval, regulations that would best apply for safe discharges of radium to public waterways.
..when EPA assessed the risk of regulated radioactive industrial discharges to public waters, it used a number 200 hundred times lower than DEP’s 600 pCi/L for what’s considered a safe radioactive benchmark for human health.
DEP’s report stated that because landfill leachate is subject to further treatment, like a sewage facility, before discharge, DEP “can conclude that there is currently no concern” with combined radium in treated discharges to groundwater or surface waters.
This places DEP at odds with a foremost expert on this issue.
In 2019, Public Herald spoke with Duke geochemist Dr. Avner Vengosh who told our team that a sewage authority is “not capable of treating radioactive material in fracking waste,” and that in leachate from fracking waste he would expect “salts, metals, and radioactive elements” none of which would be “retained or removed through conventional wastewater treatment plants.”
