New Paper: Soil Amendments Reduce PFAS Bioaccumulation in Eisenia fetida Following Exposure to AFFF-Impacted Soil

RemBind is proud to share a recent study led by Research Professor, Albert Juhasz at the University of South Australia, published in Environmental Pollution. The study highlights the effectiveness of RemBind in reducing PFAS leachability and bioavailability in a range of AFFF-impacted field soils.

Key Findings:

• Reduction in PFAS Soil Leachability: The research treated eight different AFFF-contaminated soils with 5% RemBind, resulting in over 99% reductions in PFAS leachability (28 analytes) for all soils tested, as determined by the Australian Standard Leaching Procedure (ASLP).

• Decrease in Earthworm PFAS Bioaccumulation: The study found that PFAS accumulation in earthworms (Eisenia fetida) was 23- to 246-fold lower in RemBind-treated soils compared to untreated soils.

These results demonstrate the efficacy of soil amendments like RemBind in reducing PFAS mobility and bioavailability, offering an immobilization-based risk management strategy for AFFF-impacted soils.

At RemBind, we are committed to advancing sustainable environmental solutions. This study not only validates our efforts but also paves the way for more effective soil remediation practices, ensuring a healthier environment for future generations.
