This article published in State Aviation Journal discusses cost-effective PFAS treatment to reduce risk at airport sites.
Article highlights:
- PFAS at airports likely to be remedied by Monitored Natural Attenuation (MNA)
- MNA will only work if PFAS plumes can be shown to be stable or declining
- Targeted in-situ sorption treatment of PFAS with PlumeStop® Colloidal Activated Carbon most effective enhancement of MNA
Remediating PFAS using an MNA approach at airports will require demonstrating minimal exposure to these chemicals now or in the future through groundwater plume monitoring. MNA can be a practical and cost-effective remedial path toward site closure but only if PFAS plumes can be shown through monitoring to be stable or declining. However, without enhanced attenuation interventions, it is unlikely that stable-or-declining-plume conditions will be met due to PFAS’s extraordinary persistence and mobility.
