Thank you so much for subscribing to and reading the What's New With PFAS This Week Newsletter!
Last week I attended the AWMA Science of PFAS conference in Raleigh--much more on the conference in some posts later today. Definitely a worthwhile event to attend.
In a typical week more than 100 peer reviewed PFAS related articles are published--below is a small sample of recent articles.
PFAS covers many different subject areas--ranging from wastewater treatment to law to fashion.

Abd Mutalib, N., et al. (2025). "Maternal perfluoroalkyl and polyfluoroalkyl substances (PFAS) exposure and preeclampsia: a systematic review and meta-analysis." BMC Pregnancy Childbirth 25(1): 279.
Thus, the current study conducted a systematic review and meta-analysis of the epidemiological evidence linking maternal PFAS exposure to preeclampsia.

Barraud, E., et al. (2025). "A Coarse-Grained Model Describing the Critical Micelle Concentration of Perfluoroalkyl Surfactants in Ionic Aqueous Phase." Langmuir.
In this study, dissipative particle dynamics (DPD) simulations were employed to determine the critical micelle concentration (CMC) of perfluoroalkyl and polyfluoroalkyl substances (PFAS) in ionic aqueous solutions.

Beck, I. H., et al. (2025). "Prenatal PFAS exposure associates with DXA assessed markers of adiposity in 7-year-old children from the Odense Child Cohort." Environ Res: 121394.
This study aimed to investigate the association between prenatal PFAS exposure and markers of adiposity in 7-year-old children, focusing on potential sex-specific differences.

Blomberg, A. J., et al. (2025). "Estimating historical PFAS exposures in Ronneby, Sweden using biobanked dried blood spots from newborns." Environ Res: 121397.
To investigate the start of PFAS exposures in the Ronneby population and changes over time by measuring PFAS in dried blood spots (DBS) collected from infants after birth and biobanked at the Swedish Phenylketonuria (PKU) Biobank.

FORMER NAS ALAMEDA SITE COST-EFFICIENTLY TREATED FOR PFAS IMPACTS
Historical firefighting activities at the former Naval Air Station (NAS) Alameda resulted in high PFAS (per- and polyfluoroalkyl substances) concentrations in the groundwater, threatening the Oakland Inner Harbor. In response, the project team, comprising Bayside Engineering, Construction, Inc. (Bayside), APTIM Federal Services (APTIM), and REGENESIS?, collaboratively implemented a 720-foot in situ permeable reactive barrier (PRB) using PlumeStop? colloidal activated carbon (CAC) technology. This innovative approach created an adsorptive barrier within the polluted aquifer, effectively capturing PFAS and preventing their migration. After one year, the target PFAS compounds were reduced by more than 99% in the treatment zone with significant decreases in the downgradient wells.

Navigating PFAS Legal Challenges: Key TSCA and CERCLA Insights - Webinar Recording
PFAS legal expert, Brian D. Gross, Partner (MG+M Law) presented the latest regulatory update on CERCLA and TSCA in a FREE webinar sponsored by REGENESIS. Mr. Gross was joined by REGENESIS' Maureen Dooley, Vice President Industrial Sector who presented on proven and cost-efficient in situ PFAS treatment solutions to immediately respond to PFAS impacts on sites.?
Highlights Include:
- TSCA PFAS reporting requirements?- Who must report, what they must report, when they must report, and strategies for due diligence to ensure compliance
- CERCLA?- EPA's promulgation of Maximum Contaminant Levels for PFAS in drinking water, and legal challenges to these rules
- U.S. Supreme Court?- Recent abrogation of the "Chevron Doctrine" and its likely impact on legal challenges to EPA's regulatory efforts
