Abstract Field data from various copper monitoring studies and Lead and Copper Rule compliance data are often inappropriate and misleading for reliably determining fundamental chemical relationships behind copper corrosion control. A comprehensive solubility model for copper in drinking water has been developed, that is consistent with available data for copper dissolution and precipitation. The concentration of Cu(I) is dominated by Cu2O(s) or CuOH(s) solid phases, plus soluble aqueous ammonia and chloride complexes. Utilities may choose to add DIC for buffering of pH, raising copper to some degree. Sufficient orthophosphate may reduce cuprosolvency below pH 8. Sulfate may either lower cuprosolvency under some conditions, or interfere with oxide/hydroxide passivation above about pH 8. Dissolved oxygen and chlorine residual influence copper stagnation profiles.
