Based on extensive experimental site investigations a kinetic model was developed for simulating copper in drinking water systems (CiDS). CiDS allows for the simulation of copper concentration in plumbing systems. The fundamental equations of the model are the dissolution of copper due to corrosive oxidation during stagnation periods and the solubility equilibrium of the water, with respect to malachite. The model is used to investigate the cuprosolvency of drinking water supplies, dependent on water compositions, stagnation period and pipe ages. This allows the calculation of the influence of different water treatment processes on copper byproduct release in drinking water systems. Includes 16 references, tables, figures.
