A 12-month study of six residential brass kitchen faucets was conducted to determine
total and particulate lead and selenium leaching at various stagnation times as well as continuous
long-term simulated residential use at the Portland Water Bureau's Water Quality Laboratory.
The faucets were selected to represent varying lead content and included one faucet
manufactured with Envirobrass, a brass alloy with a lead content <0.25%. The maximum initial
lead release from the faucets was calculated between 1 ¿¿¿¿¿¿¿¿ 2 µg/L in an aggregate 1-L sample,
with most faucets having lead release between an even lower 0.1 and 1 µg/L. The results also
found that identical faucet lead release varied by a factor of nearly two and that the Envirobrass
faucet leached lead at very low, though detectable, concentrations. Finally, continuous use of the
faucets for 91 days, to date, found slowly decreasing lead release due to the long-term
passivation of the faucet interiors. Selenium release was found to be low to non-detectable in all
samples from the Envirobrass faucet. Includes 3 references, tables, figures.
