Abstract
Since the 1930s, the modern science of aqueous iron corrosion has been established by scientists like J. O'M. Bockris, M. Cohen, U. R. Evans, Y. M. Kolotrykin, G. Okamoto, M. Pourbaix, H. H. Uhlig, or K. J. Vetter. Yet, the electrochemical nature of aqueous iron corrosion is seriously questioned by flawed science. Especially, metallic iron (Fe0) was mistakenly introduced in the 1990s as an environmental reducing agent. Fe0 was then successfully used in subsurface permeable reactive barriers to treat contaminated groundwater. This commentary recalls that observed contaminant degradation/reduction is not the cathodic reaction simultaneous to iron oxidative dissolution. It is concluded that the Fe0 remediation community is working against creativity and innovation.
