As PFAS regulations evolve, many organizations are moving beyond site investigation and asking the next critical question: What remediation approach is most effective for my site? From source areas that continue to release PFAS into groundwater to plumes migrating beyond site boundaries, selecting the right combination of chemistry and delivery technology can significantly influence project performance, cost, and long-term liability.
In this webinar, attendees will learn how combining remediation chemistry with multiple delivery approaches effectively addresses PFAS impacts in both source zones and groundwater plumes.
Key Learning Points:
- Plume migration control using Cascade's ColloidalChem™, a colloidal activated carbon that can be injected to form permeable adsorptive barriers in high-flux PFAS groundwater zones.
- Source zone treatment applications where soil mixing can be used to distribute stabilizers and adsorbents, throughout shallow and deep treatment intervals across a wide range of site conditions.
- GeoSierra trenchless permeable reactive barrier (PRB) technology and its potential application for emplacing activated carbon media in finer-grained formations that can be difficult to treat using conventional methods.
Why Attend
Attend this webinar to better understand how remediation chemistry, soil mixing, injectable barriers, and trenchless delivery technologies can be applied across different PFAS site conditions. You'll leave with practical insight into selecting and implementing source zone and plume management strategies based on site objectives, geology, constructability constraints, and long-term performance considerations.
