Does someone know how to test if a building is contaminated? I live in the EU and this a non-issue, but I'm afraid if/when I have to move back to my home country.
There are lead test kits with a marker like swab. You can test painted surfaces, things like dust, it takes about a minute and turns red if there is lead. A 2 pack is $11 at the hardware store here in the US. There are also test kits you wipe for lead dust, or send paint fragments and send it off to be tested. In many areas these are free or subsidized by the local government. In the US a non subsidized test kit is around $5 to buy, and around $30 to send to a lab.
Also lead paint can be safely "encapsulated" and painted over in most cases. It is really only an issue for door frames or window frames where the paint can turn to dust, or where paint is peeling or chipping.
I was hoping to see some recommendation on Water filter or other ways to get clean water. But so far there are none.
We are in 2022 and clean water still feels like a luxury.
