Modeling issues of copper solubility in drinking water

Historically, uniform copper corrosion has been of little concern. Numerous forms of pitting corrosion and consequent pipe failures have been documented and classified. Recently, because of the monitoring introduced by the Lead and Copper Rule, cuprosolvency (copper solubility) has forced many utilities to undertake corrosion control studies and treatment, rather than the replacement of pipes perforated by pitting. The development of a useful model for cuprosolvency in drinking water is constrained by several areas of uncertainty, many of which were addressed in a recent study. These areas are: the nature of ``field data;`` the selection of appropriate aqueous and solid species for drinking water systems; the uncertainties in selection of the most accurate equilibrium constant data; the role of metastable phases in cuprosolvency control; the effect of temperature; and residual oxidants in the plumbing systems.
