If you go to the blm website, you can read the entire report. I browsed through it a couple months ago, but didn't see anything that would cause alarm. It's like "there's lead in paint from the 70's" could it cause an issue? Yes, but are you really going to go around lickin the walls in your disco home? I sure hope not. Is arsenic bad for you? Yes, but it's also naturally occurring.
The difference between stupidity and ignorance. Ignorance is doing something wrong and not knowing better. Stupidity is knowing better, but doing it anyway. Don't be stupid!
