If the remaining lead is caused by the pipes inside the houses, how come this problem is isolated to Flint? Shouldn't there be the same level of lead all over the US? Maybe they are only measuring lead levels in Flint, because it was they were very high at the beginning.

The water coming in was acidic enough for the local hospitals to complain about their stainless steel sinks rusting from it. Even if there was no lead in any of the pipes they would have had to replace the entire water system because it ate right through their steel pipes which otherwise had been coated in mineral deposits to protect it.
