@Kevin D Pem - The poisoning of the public with flouride in drinking water also has an "extra dark aspect" in that the flouride used in municiple water is from furnace waste. There is mercury, cadmium, you name it as "trace elements" from whatever got incenerated at the disposal by fire business's furnace.
All those heavy metal trace elements are just below the health ecpodure limit, we get told. Not very reassuring..
The waste disposal incinerator industry does appreciate having the hazardous waste tailings disposal expense reduced by selling it for putting into drinking water, tho!
