The issue is far from localized to the US. A third of water in Canada is above the more reasonable 5ppb limit here. Many global south countries don't even really bother with testing for things like lead or cadmium because there are far more prevalent contaminants to worry about.
So, yeah. Like 1/2 of the world is basically just letting kid's brains melt from lead and doing nothing about it. Test your own water, you're likely to be surprised.
And plane heads have been crybullying an entire planet into allowing them to keep blasting leaded AVGas exhaust directly into the atmosphere where it's most poisonous for the most people. We've had a functional unleaded Aviation fuel with 80UL since 1981 and these dudes just keep screaming "Waaah you're making my casual hobby less fun! What about all those poor farmers who have to fly their own planes to cropdust, are you gonna force them to buy a new plane???" Even though that's bullshit, the excuse has been working for 40 years! 91UL has been commercially available since 2003, and nobody even cares that it requires at worst a retune.

50 years of leaded gasoline probably didn't help, and it's still used for small propeller airplanes
