EPA data shows US toxic PFAS waste problem is worsening, watchdog group says

By Shannon Kelleher

The average amount of waste containing toxic PFAS chemicals that is shipped around the US each month has almost quadrupled since 2018, according to an analysis of government data by a watchdog group.

The Environmental Protection Agency (EPA) data points to about 10,344 shipments totaling almost 27 million kilograms of per- and polyfluoroalkyl substances (PFAS) waste in the last five years, since the agency first began collecting the data.

The findings, released Nov. 9, reflect “a small percentage, we believe, of the amount of PFAS waste that is being generated, transported, stored, and disposed of in the US,” said Tim Whitehouse, executive director of the watchdog group Public Employees for Environmental Responsibility (PEER), which authored the report. “There’s no reporting requirement.”

The EPA data supports the need for the agency to regulate PFAS under the Resource Conservation Recovery Act (RCRA) Subtitle C, which authorizes the agency to set regulatory standards for the management of hazardous waste from “cradle to grave,” says the report. PEER and the Environmental Law Clinic at Berkeley, on behalf of the Green Science Policy Institute and community groups around the country, petitioned the EPA in 2019 and 2020 to regulate PFAS as hazardous waste.

The EPA did not respond to request for comment.

Exposure to PFAS “forever chemicals,” which do not break down naturally, has been linked to health problems including thyroid, kidney, and testicular cancer, as well as ulcerative colitis, high cholesterol, and hypertension during pregnancy. About 97% of Americans have PFAS in their blood, according to the Centers for Disease Control. People are exposed to the chemicals in water or food, the air they breathe, or from using products made with PFAS.

Banned carcinogen found in 88% of household objects, says new study

By Grace van Deelen

A banned chemical that potentially causes cancer in humans has been discovered in a wide array of household products, according to a study out today.

Short-chain chlorinated paraffins (SCCPs) are a group of chemicals that are used in metalworking and the production of PVC, plastics, rubbers, and other materials. They are persistent chemicals, meaning they don’t degrade in the environment and accumulate in animals. Chlorinated paraffins have been detected in various wildlife and in human milk and blood. The 2017 Stockholm Convention listed SCCPs under their Annex A, which urges the elimination of the chemicals. SCCPs were largely prohibited in Canada in 2013 and in the US in 2012.

A study published today in the journal Environmental Science: Processes & Impacts, shows that SCCPs are still widely present in household goods, indicating the need for more regulatory action. Researchers found SCCPs in 84 of 96 household goods tested in Canada. All the household goods were purchased at least one year after Canada’s prohibition of the chemical went into effect, suggesting that chemical regulation against SCCPs has not been entirely effective.

“We found [SCCPs] in almost everything, which was very surprising to us,” said Steven Kutarna, a PhD candidate at the University of Toronto and the lead author of the paper.
