I have mentioned time and again that I live in Missouri, and post shit in s/Missouri - where have you been? My point was made with reference to my experience (ie: water line construction I am familiar with). Your experience may vary. However in practice, east coast cities embraced new materials and technologies before the flyover states. If your street has ever been reconstructed, it's possible the services were replaced by the city and they didn't update their records (I mean, they don't know what's there now so...). Look up the water quality report for pH info and move forward from there. If you feel your service is probably lead AND the pH of the water is low (< 7), start drinking bottled water or get a Brita water pitcher filter, etc. With 1905 construction, lead service line materials are probable. Makes knowing the pH of your water even more important.
