Webinar | Lessons Learned in Applying PFAS Adsorption Technologies to Surface Water and Groundwater

May 10 @ 12:30 pm - May 11 @ 1:30 pm EDT


Join us on May 10, 2023 for a technical webinar regarding Lessons Learned in Applying PFAS Adsorption Technologies to Surface Water and Groundwater.


Per- and polyfluoroalkyl substances (PFAS) are a class of emerging contaminants that are being detected in a variety of matrices, including groundwater and surface water, due to widespread historical use. As PFAS continues to emerge as a major environmental contaminant, Parsons has been optimizing treatment technologies over the past 15 years to provide the most efficient solution for impacted
groundwater and surface water at various sites.


Parsons has performed over 30 bench and pilot scale treatment studies to evaluate a range of PFAS sorbents and ion exchange media including various granular activated carbon (GAC) media; ion exchange resins; and bentonite-based sorbents. Our pilot studies have informed full-scale designs that are currently in operation treating C8, C6, and a number of other target PFAS compounds in surface water, groundwater, and stormwater matrices.

Results/Lessons Learned

We will present a range of findings from our studies of treatment of PFAS-impacted water. Real data will be presented comparing GAC adsorption with ion exchange media in a variety of background water matrices. Information will also be provided regarding the scale-up of bench and pilot scale data to full-scale systems, along with unique lessons learned associated with the operation of such systems. Full-scale design optimization practices will be discussed that have been proven and are continuing to evolve to meet regulatory standards.
