“We have to explore new materials and more corrosion resistant alloys,” says Sigrun Nanna Karlsdottir, a professor of industrial and mechanical engineering at the University of Iceland.

Acute heat and corrosion eventually destroyed the well.

Environmental groups contend that federally mandated corrosion protection was not effective on the 30-year-old pipeline, and say it will never perform safely.

He said work crews have already started the process of repairing about 100 “anomalies” — areas of corrosion, cracks or other defects — to ensure that the pipeline will be in an “as-new” condition.

"Analysis of the domestic hot water pipework has indicated erosion corrosion and galvanic corrosion to be the cause, pseudomonas is not a factor."
