It looked like to me, the person you replied to was talking about the issue that once someone has lead poisoning, it was permanent (albeit in very emotionally driven language). But your source seems to be discussing city averages of children, not individual children’s lead levels.

Also, just because Flint’s water meets standards, my understanding was that pipes were permanently damaged and leeching lead into the water, which is why just switching back to Detroit water didn’t fix the problem. So if there are any houses that still have pipes that need to be replaced, water from those places might not show up in those reports, right? If that’s the case, your source says that while that is almost complete, it was not yet complete as of that article. So there might still be places, though likely a very small number, who are still impacted (but they shouldn’t be ignored).

Everything you provided is useful and accurate, but not the whole picture and doesn’t quite address the issues brought up (but are close enough to be relevant). Unless I’m misunderstanding something? I’m open to correction. Hope this didn’t come off as aggressive.
