Role of Chloride in Galvanized Iron Plumbing Corrosion and the Use of Fingerprinting Methods to Identify Water Lead Sources
… and this change could be problematic for galvanized iron pipe (GIP) installed in consumers' homes and buildings. The higher levels of chloride might increase the rate of galvanic corrosion between the sacrificial zinc coating and the underlying iron (steel) pipe. There are also concerns …

Practical Impacts of Galvanic Corrosion in Water Service Lines and Premise Plumbing
… with stopping galvanic attack between copper:galvanized iron and copper:lead via use of dielectrics have also been raised. Galvanic corrosion can be effectively stopped by isolating the dissimilar metals; however, completely eliminating electrical continuity may not always be practical or …

Several new methods for the development of latent and blood fingerprints
… to a limited extent on aluminium drink cans and galvanized iron. The use of the two and three ringed analogues of ortho-phthalaldehyde (OPA) for the fluorescent enhancement of latent fingerprints was also investigated. Solution trials proved that the reaction products of …

Nitrification in premise plumbing and its effect on corrosion and water quality degradation
… that are reactive with chlorine such as iron pipes, the relative efficacy of chloramine versus chlorine depends on the relative rate of corrosion and rate of nitrification. High rates of corrosion and low rates of nitrification favor the use of chloramine versus free chlorine in …
