WebJun 22, 2024 · In addition, to address a disinfection byproduct violation, the water operators switched from sulfate-based to chloride-based coagulants, increasing the chloride to sulfate mass ratio (CSMR) in the water from 0.45 to 2.04, which is above the critical trigger threshold of 0.5 that sometimes predicts accelerated galvanic lead corrosion problems. WebThe parameter is the simple ratio of chloride to sulfate in mass units: CSMR = (Cl - mg/L)/(SO 4 2- mg/L) The reasoning behind this formulation is that Pb solubility is greatly increased by the presence of dissolved chloride, but elevated sulfate causes the precipitation of an insoluble lead sulfate, anglesite.
