Description
Microbial activity may catalyse corrosion by otherwise kinetically hindered oxidising agents. The most likely process is microbial reduction of groundwater sulphates to sulphides, and reaction of iron with dissolved sulphides. The potential for microbial corrosion is extremely small because of lack of viability of microbes in bentonite.
