Durability of Sorption of Per- and Polyfluorinated Alkyl Substances in Soils Immobilized Using Common Adsorbents: 2. Effects of Repeated Leaching, Temperature Extremes, Ionic Strength and Competing Ions
Science of the Total Environment
Two PFAS impacted soils from Defence sites in Australia were treated with RemBind®.
Test methods accepted by regulatory authorities worldwide were used to assess the long-term stability of the RemBind under multiple leaching scenarios.
The effects of ionic strength, organic matter, and temperature extremes were also tested to simulate worst case scenario conditions in the field.
Results showed that remediation with RemBind® will be stable for extended periods under a wide range of site conditions.
This study provides site owners and regulatory authorities with a high level of confidence that the binding of PFASs by RemBind® is predicted to be persistent in the long term.
