Abstract Plumbing products made of brass and similar alloys are the only lead containing materials still installed in drinking water systems and, by law, may contain up to 8% lead. Brass ranges in metal composition depending on its application. Brass is composed of approximately 60 to 80% copper, 4 to 32% zinc, 2 to 8% lead, 6% tin, and trace amounts of iron, tin, and cadmium. The relationship between alloy composition and resulting amounts of metal leached from the alloy in drinking water has not been fully established. Better understanding brass corrosion may provide information and guidance to the use of the safest materials for the production of plumbing fixtures, and optimization of corrosion control treatments. This study examined the effect of alloy composition, pH, orthophosphate, and stagnation time on the metal leached from 6 different brasses and the pure metals and make up brass (lead, copper, and zinc) in Cincinnati, Ohio, tap water.
