Triangle utility wins nearly $2M to treat PFAS ‘forever chemicals' in water

A nearly $2 million payout was awarded to OWASA customers for treating PFAS contaminants in Chapel Hill and Carrboro's drinking water, the local utility said Thursday. Another $1 million payout is possible in the future, in addition to smaller awards from lawsuits filed against other manufacturers, including Dupont, Chemguard Inc., and BASF Corp., OWASA officials said.

Rely FX Releases Fluorine-Free Portable Foam Fire Extinguisher

Rely Innovations has introduced the first UL listed portable fluorine-free foam extinguisher that meets NFPA-10 standards. The new Rely FX P2.5SFFF (Synthetic Fluorine Free Foam) extinguisher uses NUFOAM, a PFAS-free foam agent solution that provides effective extinguishment and suppression for Class A and Class B fires. The premixed solution maintains its integrity for five years, aligning with the extinguisher’s required hydrostatic testing cycle and lowering lifetime service costs.

Maine DEP Issues Initial Currently Unavoidable Use Determinations for PFAS-Containing Products Subject to Impending Sales Prohibition

Maine has completed a regulatory process and has adopted updates to its PFAS in products rules to identify two approved Currently Unavoidable Use (CUU) exemptions from the state’s phased ban on in-state sales of products with intentionally added PFAS. The exemptions include the Cleaning product container internal cartridge valves (HTS 3926.90.4510) used in industrial sectors.

Williamtown PFAS levels could be impacting male reproductive health

New research from the University of Newcastle has revealed PFAS levels matching those found in the Williamtown contamination zone could significantly alter male reproductive health in animals. The study, co-led by Professor Brett Nixon highlights a potential new mechanism of harm: PFAS may not directly damage male reproductive health, but instead alter the molecular signals sperm carry – crucial for healthy embryo development.

Electrochemical Oxidation of Perfluorooctanoic Acid on a Bi2O3–SnO2/Ti4O7 Reactive Electrochemical Membrane: Application to Groundwater Treatment with Mechanistic Insights

This study investigated electrochemical oxidation of perfluorooctanoic acid (PFOA) using a Bi2O3–SnO2 catalyst supported on a Ti4O7 reactive electrochemical membrane (BTO/REM). In an inert NaClO4 electrolyte, the BTO/REM achieved 98.1 ± 0.4% PFOA removal, 85.6 ± 3.6% fluoride yield, and 94.4 ± 4.6% total fluorine balance at 4.2 V/SHE and a 60 s hydraulic residence time (tr). Perfluoroalkyl carboxylates (PFCAs) with three to six perfluoroalkyl carbons formed at a combined yield of 15.3 ± 2.6%. In real groundwater, PFOA removal was limited (?1%) due to low ionic conductivity, but adding NaClO4 increased removal to ?91% at 4.7 V/SHE with tr of 15 s.

Historical Blood Serum Samples from Wilmington, North Carolina: The Importance of Ultrashort-Chain Per- and Polyfluoroalkyl Substances

This study highlights that ultrashort-chain PFAS dominated the PFAS signature in serum samples of Wilmington, NC, residents collected between 2010 and 2016. At the measured serum levels, ultrashort-chain PFAS may be an important contributor to PFAS-associated toxicity.

Upcycling PVDF into Carbon Electrodes for Zinc-Ion Supercapacitors to Avoid Its Entry into the Ecosystem

Per-and polyfluoroalkyl substances (PFAS) pose a global threat due to their environmental persistence and bioaccumulation. Polyvinylidene fluoride (PVDF), as a high-performance fluoropolymer, is indispensable in many fields and cannot be completely phased out in the short term. This has led to a dilemma between the necessity of PVDF and its environmental risks throughout its life cycle, which has become a core bottleneck in the regulation of fluorochemicals. In light of this, this study converts recycled PVDF into microparticles for application in the field of supercapacitor energy storage. The prepared electrode with PVDF micro-particles not only achieves an ultra-high mass loading of 100 mg cm?2, an ultra-high specific capacitance of 31.4 mAh cm?2, and ultra-long cycling of more than 15 000 cycles, but also realizes an ultra-high energy density of 29.7 mWh cm?2.

Pyrene-Based Multicomponent Metallacages for Highly Efficient Adsorption and Photocatalytic Degradation of Perfluorooctanoic Acid

The remediation of perfluorooctanoic acid (PFOA) remains a critical challenge due to its exceptional chemical stability and bioaccumulation risks. Here, we present two pyrene-based multicomponent metallacages that synergistically integrate high-capacity adsorption and photocatalytic degradation of PFOA. The 4,4’-bipyridine tetracarboxylate-derived metallacage demonstrates a high PFOA adsorption capacity of 1223 mg/g, facilitated by multivalent electrostatic interactions and hydrogen bonds. Subsequent photocatalytic treatment of the preconcentrated PFOA achieves 91% defluorination within 6 h through a superoxide radical-mediated chain-shortening mechanism, as verified by electron paramagnetic resonance and intermediate analyses.
