Abstract

The overall goal of this research was to provide an improved understanding of the chloride-to-sulfate mass ratio (CSMR) considering chloride and sulfate variations at full-scale water treatment plants and corrosion potential under simulated premise plumbing conditions. The specific objectives were to (1) track changes in chloride, sulfate, and natural organic matter (NOM) through full-scale treatment plants that use the magnetic ion exchange (MIEX) process; (2) determine the effect of varying chloride and sulfate concentrations at constant CSMR on lead release; and (3) determine the effect of NOM composition at constant CSMR on lead release. Major conclusions of this research include that MIEX treatment increased the chloride concentration, decreased the sulfate concentration, and thereby increased the CSMR, and high concentrations of chloride and sulfate yielded significantly greater lead release than low concentrations of chloride and sulfate, despite a constant CSMR of ∼0.5.
