If I'm not mistaken, older galvanized steel plumbing pipes had lead as part of their ingredients. Apparently it was a contaminant in the zinc galvanizing.
I had the service line to this home replaced around 1998. The home was built in 1941; I bought it around 1997. The original one was galvanized steel which had eventually failed and was leaking. Later I also replaced the galvanized steel water lines to the kitchen and fridge with copper.
Lead sucks.
