Abstract
- Over the past three decades, groundwater remediation using permeable reactive barriers (PRBs) has proven to be effective. The majority of installed PRBs uses metallic iron (Fe(0)) as a reactive material. However, the success of implemented Fe(0) PRBs is yet to be rationalized as Fe(0) is a generator of iron oxides (contaminant scavengers) and secondary reducing agents (e.g. Fe(II), Fe3O4, H2, green rust), This communication demonstrates that Fe(0) is not an environmental reducing agent. Therefore, more science-based investigations are needed to optimize the operation of Fe(0) PRBs. In particular, Fe(0) PRBs and Fe(0)-based water filters should be regarded as particular cases of “metal corrosion in porous media”. A key feature of such systems is that the extent of Fe0 corrosion temporally depends on the residual porosity (capillarity). Thus, the functionality of any Fe0 PRB should be monitored in a way that the time-dependent variation of the kinetic of iron corrosion is discussed.
