Brass fittings – as a source of lead in drinking water Stage 2 - WT2202

Description
This project is to help assess the amounts of lead leached from brass fittings. Lead in drinking water has been a long term issue in the UK and, as standards have progressively decreased the Prescribed Concentration Value (PCV), achieving compliance has presented greater challenges. The principal sources of lead in drinking water are the presence of lead service pipes and plumbing and to a lesser extent lead-based solders. Both are now banned for use in new installations but continue in use in older installations. Some compliance infringements occur in the absence of lead pipe or solder and may be caused by lead from brass fittings. The information from this project will assist in developing strategies for the water industry and regulators to continue reducing lead levels in drinking water.
Objective
The purpose of this study is to understand the potential contribution of brass fittings to lead levels in drinking water, and to inform how this may affect the development of national and local strategies to reduce lead levels in drinking water.
