Dynamic templating as a result of cathodic hydrogen gas production is suggested as a possible mechanism for the formation of tube-like corrosion products on an unlined cast iron pipe in a drinking water distribution system. Mounds of corrosion product, with protruding tubes and freestanding tubes, were observed within a single 30 cm section of piping. Internal morphologies for all shapes were texturally complex although mineralogically simple, composed of two iron oxide/oxyhydroxides minerals: {alpha}-FeOOH (goethite) and Fe{sub 3}O{sub 4} (magnetite). Static templating by either microorganisms or minerals was rejected as a possible mechanism for tube formation in this study.
