I believe the same thing happened around the turn of the century somewhere in Pennsylvania? In that case it just affected one section of the distribution grid, not the entire city. Somewhere on the order of a thousand kids. IIRC they got free testing and I think some health care for life.
I just bought an old house with known lead paint. I had as much remediated as I could but there is still (covered) lead paint on the radiators, door casings, stairs, soil and porches.
What sort of exposure does this provide my children? How likely are these to be airborne? How much ingested lead dust is necessary to affect my children's blood levels?
We had a baseline blood test before we moved in, but now it's just waiting 4 months until their updated test, and me being an anxious mess and wiping everything down and touching up paint constantly.
For the same reason why Flint water trough lead pipes was good for decade turned dangerous very quickly after one change.
The questions you asks have answers. Those answers are clearly communicated in the news and research. They are basic information by know for anyone interested.
Just asking them reveals that you don't follow issues. This is not a good way to be skeptic.
Good see don't you feel that dopamine, doesn't it feel good to be angry about things your identity is invested into.
