Description
We are applying a new conceptual framework based on solid-state mineral chemistry. We are developing our understanding of BMAD of the persistent chlorinated solvents PCE and TCE. We are investigating BMAD of PCE and TCE by magnetite, Fe sulfides and Fe-bearing clay minerals.
We are carrying out laboratory-based experiments with synthesized pure minerals. We are also using sediment from contaminated sites. At Newcastle, we focus on the role of clay minerals and clay mineral iron reactivity for chlorinated solvent degradation.
The project won the SERDP 2018 Project of the Year Award for Environmental Restoration.
