I dont know, but as general commentary:

Lead poisoning is not so easy to fix. You have to replace extensive amounts of lead pipe and/or find and remedy another source and then treat the existing poisoning which doctors aren't so talented at.

Most doctors aren't well versed in chelation protocols. Even if you replace all the lead pipes, the problem isn't resolved. You still need medical care.

My understanding of the Flint water issue was the introduction of corrosive water that caused the lead pipes to leech lead. The fix wasn't "Make repair at the one point of failure" but "Replace every water pipe in the 34.1 square mile city."

Flint had to replace their pipes before it could be fixed. But it was fixed in 2019, anyone who still posts “the US is bad because Flint doesn’t have working water” is just lying to you.

What do you mean? Flint is still replacing lead service lines as they're found.

Merely having lead pipes isn’t the problem as long as they’re not degraded. As I said, the water quality has been fine for years now.
