SERDP & ESTCP have selected a project led by Dr. Chuck Newell with GSI Environmental Inc. to develop methodologies for assessing mass flux of #PFAS at sites with impacted #groundwater. The project team aims to demonstrate how targeted, high-quality data can be used to refine conceptual site models and develop and screen remedial alternatives. Additional details are available on his project web page. https://bit.ly/3ZJ6uaA

Research and technology development to characterize, treat, and manage PFAS-impacted sites for the DoD.
关于我们
The Strategic Environmental Research and Development Program (SERDP) and the Environmental Security Technology Certification Program (ESTCP) lead the Department of Defense’s PFAS-related research and development efforts. Since 2011, the programs have funded hundreds of projects that have quickly and significantly advanced our understanding and management of PFAS in the environment. This LinkedIn account provides updates on the latest PFAS-related projects, reports, and publications from SERDP and ESTCP. To access the database of PFAS-related projects and resources, visit the PFAS Focus Area on the SERDP & ESTCP website.

Congratulations to Kate?ina Litvanová for her publication on thermal decomposition products of #PFAS! Results from this manuscript were support by two #SERDP projects led by Dr. Feng "Frank" Xiao at the University of Missouri-Columbia. Additional details on these projects can be found on the SERDP & ESTCP web page (https://lnkd.in/gvtMhCMd and https://lnkd.in/gfttj8wj)
Check out our new publication called “Investigation of Real-Time Gaseous Thermal Decomposition Products of Representative Per- and Polyfluoroalkyl Substances (PFAS)” published in the Journal of the American Society for Mass Spectrometry (ASMS) and with ACS Publications. In this work I explore thermal breakdown of various PFAS using pyrolysis. In this?innovative method we combined evolved gas analysis - mass spectrometry (EGA-MS) for fast real-time screening with thermal desorption - pyrolysis - gas chromatography with mass spectrometry (TD-Py-GC-MS) for detailed investigation of breakdown products. This method provides wide range of information about the behavior of PFAS and helped to identify new yet unknown breakdown products. Huge thanks to the coauthors Alena Kubatova, Bethany Klemetsrud and Feng "Frank" Xiao for their help and contribution in the process and I also want to thank Nafisa Bala for her instrument support. Make sure you check out our Supporting section as well, there’s tons of useful information we couldn’t fit in the main manuscript!

To advance research into thermal treatment of #PFAS-impacted material, SERDP & ESTCP have funded a novel project led by Dr. Kyle Doudrick, Ph.D., P.E.’s at the University of Notre Dame. Dr. Doudrick’s project aims to better understand the behavior of PFAS during thermal treatment to enhance the management of PFAS-laden wastes as well as regeneration of spent adsorbents. Additional details are available on his project web page. https://bit.ly/4gYs8yN

Congrats to Dr. Jens Blotevogel with CSIRO for this new publication on #PFAS destruction based on research conducted under his #SERDP project. Full details on the project can be found on the project web page (https://lnkd.in/gwU8x4Pz)
If you are interested in PFAS incineration, please take a moment to read our new publication in ACS ES&T Engineering. In this study, we use highest-level quantum chemical calculations to reveal that it is the perfluoroalkyl chain, not the headgroup, that determines the temperatures needed for thermal destruction of #PFAS. At temperatures >950 °C and 2 seconds gas residence time, PFAS can be completely mineralized. Are we done with investigating thermal PFAS destruction then? No, because recombination reactions and mixing need to be understood and controlled as well. And there are still plenty of opportunities to improve the efficiency of the process. But if done right, incineration will be a viable tool in the toolbox of destructive technologies. https://lnkd.in/g_eczryB

Congratulations to Grant Carey with Porewater Solutions on a new publication providing additional information on in situ remedation of #PFAS-impacted #groundwater, based on results from two #SERDP projects. The SERDP projects are led by Matt Vanderkooy with Geosyntec Consultants, Dr. Neil Thomson with the University of Waterloo, and Dr. Xitong Liu with The George Washington University. Additional information on these projects is available on the project web pages (https://lnkd.in/ePwbDSsH and https://lnkd.in/ePCDNZrR).
We are pleased to announce the publication of another open access journal paper: Modeling the Influence of Coastal Site Characteristics on PFAS In-Situ Remediation, published in Ground Water.?(Free download:?https://lnkd.in/exFABnuQ Thanks to my co-authors for their invaluable assistance with this study! Anthony Danko, PhD, PE (NAVFAC EXWC) Anh Pham (University of Waterloo) Keir Soderberg (S.S. Papadopulos & Associates, Inc.) Beth Hoagland (S.S. Papadopulos & Associates, Inc.) Brent Sleep (University of Toronto) And many thanks to SERDP & ESTCP and PFAS-Related R&D Efforts, SERDP & ESTCP for their continued support. In this paper, we used the Porewater Solutions In-Situ Remediation Model (ISR-Model) to evaluate the influence of tidal fluctuations and groundwater flow direction reversals on PFAS remediation in a colloidal activated carbon (CAC) barrier installed near the shore.?Coastal hydrogeology used to support groundwater flow modeling is based on an actual site. This paper also assessed the positive influence that increased ionic strength at coastal sites will have on PFAS adsorption to CAC, and the increased time for flushing downgradient PFAS due to enhanced adsorption to natural organic matter.?(More info on the ISR Model: https://lnkd.in/eYSs-ekb) Our main finding is that CAC barriers will achieve orders of magnitude PFAS mass discharge reduction at coastal sites.?The time to attain cleanup goals at the shoreline will be longer for PFOS than PFOA.?Specific site characterization methods for improving remedy design and performance predictions at coastal sites are recommended.

In situ treatment of #PFAS-impacted #groundwater can be particularly challenging. Matt Vanderkooy with Geosyntec Consultants, Inc. and Neil Thomson at the University of Waterloo are leading a #SERDP project to further our understanding of addressing such sites. ?The project team’s effort will improve the understanding of the capability of commercially-available activated carbon (AC) to immobilize PFAS in situ. Additional details are available on their project web page. https://bit.ly/4iIM22a??

We are excited to highlight another project from SERDP & ESTCP’s partnership with the Defense Innovation Unit (DIU), featuring a cohort of prototype projects aimed at addressing #PFAS-impacted #groundwater. Under this project led by Frank Cassou with Cyclopure, Inc., the effectiveness of a DEXSORB? packed-bed filtration system will be demonstrated for high capacity PFAS sequestration from groundwater, followed by desorption and concentration of PFAS. Additional details are available on his project web page. https://bit.ly/4gpnDgm

To further research into the biotransformation of #PFAS at #AFFF-impacted sites, SERDP & ESTCP have funded an innovative project led by Dr. 劉錦霞 Jinxia Liu's at McGill University. This research aims to investigate whether major nitrogen-containing PFAS found at AFFF-impacted sites can serve as nitrogen sources for microbial growth while being transformed, and whether molecular biological tools (MBTs) can assess their transformation potential. Additional details are available on her project web page. https://bit.ly/3P2pb43??
