I'm too busy to dig that stuff up, but I heard the aluminium processors on Pennsylvania, in the early days, poisoned the air by the smoke stacks releasing toxic fumes that would drift over cow pastures leaving all the cows dead. After legal battles and law suits the company's put phosphate scrubbers on the top of the smoke stacks to filter out some of the toxins. Those scrubbers get old and clogged and need to be replaced so now the old ones are toxic waste. Disposal is an expensive problem. The solution was to put the toxic fluorosilicic acid, sodium fluorosilicate, and sodium fluoride. Into the municipal water systems. Go figure...its a neurotoxin. Its super bad for the human body like mercury. Hope that helps to get you started. It's always good to look at where, when and why these practices started. https://encrypted-tbn0.gstatic.com/images?q=tbn:ANd9GcTye23MD04iH1JG-v4Gxis5h5b3swgH_cIyOA&usqp=CAU Give this neurotoxin to your kids and knock them down a few iq points, its totally disturbing. Sheep to the slaughter.
