They let a sediment coating form on the lead. We do that too, and it’s why the lead removal programs are only a top priority, and not an active emergency.
It actually works, because it’s less a lead pipe, and more a “crusty mineral” pipe, with a lead coating.
Downside being that if you damage that buildup everything goes to shit, hence the decades of working to replace the pipes.
Actually, I’ve read somewhere that they actually found out and did something for it but somehow the information got lost
