The following article was originally published in the October 2017 issue of Environmental Science and Engineering Magazine. Oxidizing and neutralizing chemicals, as well as misty, wet and damp conditions, contribute to an aggressive corrosive environment in water treatment plants. In wastewater treatment plants, there is also a corrosive cocktail of bacterial decomposition of fecal and
