Even so called "lead free" pipes were allowed to have significant lead content just a few decades ago!
What you can do is, for $75 per faucet, get your water sampled and tested by the SF water department. We did that and got back the result that there was no lead in measurable quantities. This was a great relief. Our house looks fairly renovated, so they seem to have gotten rid of those pipes, too.
This is the kind of thing that you just don't think about when moving to the US.
Also, the standard for contractors is to assume your paint has lead in it if the house was built before the late '70s. Even testing a whole house for lead paint is extremely expensive, and there's no central registry of lead results, so you're gonna have to test over, and over, and over.
For water, just to add some extra safety, we installed a reverse osmosis water filter system for our refrigerator hookup, and removed the standard refrigerator one.
If you're concerned about tracking it in from outside, or improper renovation, you can apply the tests to dust too, which is where any pulverized lead in the air would come from.
Where I live the people that do the testing are required to be different from the people doing abatement. (And once the abatement is done you can get the people that did the testing to come back out again and officially verify that the housing unit meets lead safe standards.) But US states differ in some of the details here.
And some states do indeed have a central registry of lead results. Mine does. I went online and easily found test results from the 1990’s for places I’ve lived.
They closed 2 in Philadelphia, PA in 2019 for remediation https://www.inquirer.com/health/philadelphia-lead-playground...
I hope you are aware of how we handled asbestos as well.
I remember in Germany in the 80s our elementary school got closed for a while, and the classes relocated temporarily, to rip out all the asbestos.
guess i should check into if i'm eligble for cashing in one of those mesothelioma cheques at some point
Anyways now you know why Americans seem a little 'off'
No. My apartment in CA was required to disclose to us that our apartment had asbestos in the ceiling. (And lead in the paint. $2,700/mo for the privilege!)

My rule of thumb is generally anything the EU deemed unsafe, we rounded up by %20 and said it's fine
House pipes being changed is probably 90% of the worry anyway. If it was recently enough, you might be able to pull the original permits and get a better idea of what was replaced.
