I used to have a job testing soil. We need sold numbers ppm before and after. Saying the soil is poisoned from spraying is not science. Look at the soil volume and how many tons of metal it would take....
Before, after, surface deposits and deeper samples... Penetration rates, seepage, whatever you call the rate at which stuff descends down through the soil. Yes, a spot number doesn't give you the full picture. I do get the feeling that the only soil studies permitted or funded, however, will be from the mining companies.
