Alternatives to single use plastic like paper wrappers and compostable bowls can test higher for total fluorine, owing to water and grease repellents that contain PFAS.
Fibre-based moulded bowls, which are marketed as “compostable,” had PFAS levels three to 10 times higher than doughnut and pastry bags. PFAS are added to these bowls and bags as a water- and grease-repellent.
Activated carbon is a charcoal-like substance that PFAS stick to quite well and can be used to remove PFAS from water. Ion exchange systems are typically even better, writes Joe Charbonnet.
The State has also asked the Court to void certain corporate transactions between DuPont and its affiliates designed to insulate DuPont from PFAS-related liabilities.
Numerous Maine farmers have had their livelihoods disrupted due to PFAS contamination, which originated in sludge that was spread as fertilizer by farmers who were told by the government that it was safe to use.
ASCE awarded Higgins the 2022 Samuel Arnold Greeley Award for a paper he co-wrote with colleagues that include Colorado School of Mines PhD candidate Stefanie Shea.
Groups call for a prohibition on Inhance Technologies from continuing to produce several dangerous per- and polyfluoroalkyl substances (PFAS) during the fluorination of plastic containers.
The winner of the 2018 Stockholm Water Prize, often described as the Nobel Prize for water, Rittmann is a pioneer in the use of microorganisms for wastewater treatment.
Study examines remediation at a site that began in the 1990s, with groundwater monitoring since 2000, including measuring for PFAS and PFOS since 2015.
About half of all sewage waste in the U.S. is treated and converted to biosolids, a further half of which is used as fertilizer after additional processing.
In a paper published in the journal Environmental Science: Processes & Impacts, scientists showed how PFAS can leach out of fertilizer made from recycled waste with the help of microbial decomposition.
