  Mostly what I'm aware of in the US is lead pipes from the water main in the street to the house. A fair amount of leaded solder in copper pipe joints, but lead pipes in the house is pretty uncommon. As I would understand it, maintaining a neutral to alkaline pH in addition to the chlorine/chloramine used for disinfection of potable water generally produces a fairly durable passivization layer on lead which prevents significant lead exposure in drinking water. Responsible water utilities deliberately prevent the distribution of acidic water AND do some sort of at-the-tap water testing program as well. Needless to say, in Flint, Michigan, they screwed up at these things.
