Lead plumping is already absent in almost all homes in the US (except for drainage purposes where still required by code in places like NYC). And water mains rarely ever used lead. The main source of lead in the water supply comes from the service lines and goosenecks that connect homes to the water mains. These would be buried deep in your front lawn. There is already some grant money that people can apply for to replace the connections in front of their house, but solving this problem for real would require utilities to systematically going house to house and digging up front yards at massive expense: ~$5k or more a pop. Ideally you could save money if you have dedicated crews just going neighborhood by neighborhood and digging up the pipes. But because you are dealing with something outside of the normal utility easement, you are going to be upsetting a lot of residents if you just rip out their yard looking for the thing. It's a pity that we don't have more community/volunteer organizations in our country that can get this kind of work done. It's something that's going to be ridiculously expensive and time consuming to have professional crews do. But the majority of the work involved is not particularly difficult or hard.
