Successful corrosion monitoring of underground pipelines in a metropolitan area requires careful use of established test methods, integrated with modern record keeping and the best data evaluation techniques possible with the use of a personal computer. Utilizing the computer for test data storage, calculations, and generation of graphs to aid data interpretation, the Metropolitan Water District of Southern California successfully manages pipe-to-soil potential and DC current information collected from its extensive water distribution system.
