At the very least, I would want to know if my house has a lead service pipe. Several years ago in my locale, the city identified every house with a lead pipe, and replaced all of them. This doesn&#x27;t eliminate lead solder used on copper pipes within the house. I suppose one could strategically identify the portion of the plumbing used for drinking water, and replace it with lead free.<p>I think Flint may have been an accident waiting to happen -- hoping that nothing would ever disrupt the passivation built up inside the pipes. I think that replacing lead service pipes nationwide sounds like a public works project. Putting the people of Flint to work replacing their own pipes would bring more than just clean water to the city.
