WebJul 23, 2024 · More specifically, we are concerned with the Chloride to Sulfate Mass Ratio (aka the CSMR), which considers the ratio of chloride ions in mg/L to sulfate ions in mg/L. Sulfates can form thin protective layers on lead surfaces that inhibit galvanic corrosion from chlorides. ... A CSMR of 0.5 or greater can lead to increased corrosion potential ... WebSep 1, 2024 · These studies suggest that a CSMR ratio of > 0.5 would enhance metal leaching. Willison and Boyer ( 2012 ) explained that increased Cl − forms soluble lead (Pb) complexes, thereby increasing Pb concentrations in water, whereas sulfate forms insoluble Pb sulfate complexes, which precipitates onto the pipe reducing further corrosion.
