Stop Using Dangerous Faucets, Regulator Warns

I remember being shocked to see a Prop 65 warning on a nozzle for a garden hose and then found out that it is routine for brass to have a little bit of lead in it to simplify machining -- energy use in turning leaded brass on a lathe is 3x less than unleaded brass. I remember brass being really easy to work with in shop class, but they didn't tell me why!
