A new assessment from the Environmental Protection Agency (EPA) on chemicals known as “GenX” chemicals that have been found in a North Carolina river show they are more toxic than a Trump-era assessment found.
The new toxicity assessment from the EPA says it’s safe for people to ingest less of the chemical than previously thought.
It’s now only safe to ingest “GenX” chemicals at a level of three-millionths of a milligram per kilogram of body weight each day.
A 2018 draft report from the agency said it was safe to ingest eight hundred thousandths of a milligram per kilogram of body weight.
The new report states in animal studies, GenX chemicals have shown impacts on the liver, kidneys and immune system, as well as offspring development and has an “association” with cancer.
Using animal studies, the 2018 draft found health impacts in the kidneys, blood, immune system and fetal development and said the data was “suggestive” of cancer.
GenX chemicals have been found in North Carolina’s Cape Fear River, which has been a drinking water source for the Wilmington, N.C., area.

GenX is part of a class of chemicals known as PFAS, which have been linked to a range of health issues. PFAS are sometimes called “forever chemicals” because they don’t break down easily and persist in peoples’ bodies and the environment.
GenX has been used as a replacement for a different PFAS chemical called PFOA. PFOA has also been linked to adverse health outcomes.
The new EPA report uses updated data since the 2018 draft — in addition to a new review process and changed uncertainty factors.
The EPA is currently planning to regulate PFOA and another substance called PFOS in drinking water.
It’s not clear whether it’ll eventually take a similar step for GenX, saying that it is “ exploring regulatory approaches for additional PFAS compounds, which may include GenX chemicals.”
It will, however, issue a health advisory in the spring for GenX, which can provide technical information to states on its health effects and treatment technologies.
