New Paper: RemBind Soil Amendments Reduce PFAS Bioaccumulation in Earthworms Following Exposure to AFFF-Impacted Soil

RemBind® is proud to share a recent peer-reviewed 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 across a range of AFFF (aqueous film-forming foam)-impacted field soils.

Key Findings

Reduction in PFAS Soil Leachability

The research treats 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 finds that PFAS accumulation in earthworms (Eisenia fetida) is 23- to 246-fold lower in RemBind®-treated soils compared to untreated soils.

These results demonstrate the efficacy of RemBind® soil amendments in reducing PFAS mobility and bioavailability in AFFF-contaminated soil, offering a proven, immobilisation-based risk management strategy for PFAS-impacted sites.

At RemBind®, we are committed to advancing sustainable PFAS remediation and 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.
