title: Copper release in low and high alkaline water.
abstract: Copper release in drinking water, caused by electrochemical corrosion of household distribution systems, was investigated. Experiments were developed testing both low and high alkaline water in stagnant conditions. The effect of varying stagnation time was investigated also. Both soluble and insoluble copper compounds, produced by corrosion processes are quantified, using appropriate experimental procedures. On the basis of obtained results, copper concentration in stagnant water is defined as a function of water alkalinity, while total metal release is defined as a function of stagnation length, and is not dependent on water alkalinity.
