This is for strictly mildly interesting material. If it's too interesting, it doesn't belong. If it's not interesting, it doesn't belong.
This is obviously an objective criteria, so the mods are always right. Or maybe mildly right? Ahh.. what do we know?
Just post some stuff and don't spam.

Nearly all land near small runways and airports that fly planes using AvGas will have lead contamination. That’s because lead is still used in most aviation fuels a consumer plane would use. Runways are also required to have and use PFAS in firefighting foam for emergencies. Training and system tests will dump that stuff in the surrounding area.
Unless these fine folks have A380s they’re paying a hefty premium for lead exposure and PFAS in their water and soil.
Lead is only one factor of pollution though. You will note that i acknowledged it exists. There is no objective way to say what is the most important factor or how you compare them.
