Lead used tp be a very common additive in gasoline. In the US there was no legislation to reduce it's use until the 1973 and it wasn't fully banned until 1996.

It can be assumed that any well-trafficked road during or before this period has substantial lead contamination.

It's still allowed in general aviation. Let your lawmakers know if that bothers you. The stakeholders in this case happen to be a small, wealthy minority.

Wealthy on a global level definitely, but as far as Americans go there are lots of relatively normal middle-income hobbyists in GA. You can buy and operate a plane for less than a used car if you're frugal about flying.
