Evaluation of Corrosion Indices for Predicting Lead Leaching in Water Distribution Systems Public
Downloadable Contentopen in viewer
Ingestion of lead in drinking water has potentially dangerous health effects. Corrosion indices are routinely used in the water industry to predict corrosion potential. We evaluated twelve corrosion indices to see how accurately they predict lead leaching, using water quality data from seven water utilities. We determined the two best indices: the Calcium Saturation Index and Stiff & Davis Stability Index. We designed a corrosion monitoring program for drinking water utilities to aid in dealing with corrosion concerns.
