Abstract [en]

Brass couplings are used in most piping systems for tap water. The alloy contain a variety of metal composition, amongst these metals lead is included. Lead is a toxic metal that can leach from brass when it is in contact with aqueous solutions. There are several physical and chemical conditions that affect the leaching of lead. Stagnation time, material composition and water quality are some of these conditions. The aim of this project is to generate a dataset that can be used for evaluation of the leaching of heavy metals from brass couplings during different hydrochemical conditions. By exposing brass couplings to synthetic waters various properties, analyse the results and comparing these to limits set by approval procedures it is possible to obtain a prediction on how the brass couplings might leach lead when installed in tap water systems. Results shows that at least one of the brass couplings included in this test could be unfit for usage in drinking water system installations.
