New Research Article Provides Guidelines for Monitored Natural Attenuation of PFAS Contaminants in Groundwater
This article by Charles J. Newell et al. published in Wiley’s Remediation Journal discusses practical guidelines based on a three-tiered line of evidence (LOE) approach for evaluating monitored natural attenuation (MNA) of PFAS. The approach outlined provides methods to assess PFAS retention in the subsurface. It also includes a list of methods to enhance MNA of PFAS plumes if MNA alone is not sufficient to manage the risk of the plume. Read the full article below.

Technical Memo from REGENESIS CEO Scott Wilson Outlines “Key Takeaways” from the Article by Newell et al. about MNA of PFAS
Below is a technical memorandum written by REGENESIS President & CEO Scott Wilson that summarizes what he sees as the “key takeaways” from this very important research paper by Charles Newell et. al. entitled “Monitored Natural Attenuation to Manage PFAS Impacts in Groundwater” (see above for a highlighted version of this article). Key takeaways include a key concept that is intrinsic to environmental risk: Environmental Risk = Hazard X Exposure. By eliminating the potential for exposure, the risk is eliminated. This is how natural attenuation works. Download the technical memo written by Scott Wilson to learn more.
Video: Understanding the In Situ Treatment of PFAS Using PlumeStop Colloidal Activated Carbon
With PlumeStop, remediation professionals gain a solution that will provide an effective, more economical means of stopping the migration of PFAS plumes, thereby protecting sensitive receptors. There are many possible remedial design strategies for the in-situ containment of PFAS using PlumeStop. This video includes a technical explanation of how PlumeStop colloidal activated carbon functions within an aquifer to purify groundwater of PFAS contamination. It also contains subtitles in multiple languages, which you can select in the settings of the video player.

Eliminate the Risk of PFAS with Colloidal Activated Carbon
In situ remediation with colloidal activated carbon eliminates risk of PFAS contamination in soil and groundwater at a low-cost. By coating flux zones of an aquifer with colloidal activated carbon, a permeable sorption barrier is created in situ, purifying groundwater as it passively migrates. PFAS constituents from up-gradient source zones are rapidly sorbed to the carbon and removed from the mobile dissolved phase. By removing PFAS from the mobile phase, the route of exposure to down-gradient receptors is eliminated, thereby eliminating the down-gradient public health risk associated with PFAS.
Sign Up for the Upcoming Webinar on Successful In-Situ PFAS Remediation at Airports
In this webinar we are pleased to have as a special guest speaker Kristen Freiburger, Associate at Shannon & Wilson. Her presentation will discuss PFAS remediation at Fairbanks International Airport, including a discussion of fate and transport of PFAS and the use of PlumeStop colloidal activated carbon. She will be joined by Maureen Dooley, Vice President – Industrial Sector at REGENESIS, who will discuss remediation solutions for petroleum hydrocarbons and PFAS at airport sites. This webinar starts Thursday, January 27th, 2022 at 11am pacific/2pm eastern.
