I wonder what happens after, say, an earthquake? Can pipes bend enough to cause cracks in the passivated layer and temporarily increase lead levels?

- kodah 5y agoYeah, they probably could, but the phosphates are always in the water so it'll reform and the amount of lead that gets into the water when disbursed is pretty low ppm (parts per million). The fundamental problem is that this infrastructure is costly to dig up and replace, and the key word here is "service lines". Those are the lines consumers are responsible for paying for. Cities that have lead lines should be working with the EPA to set milestones and goals for yearly replacements with federal funding though.
