I have researched fluorosilicic acid to death. My problem is that  you people continue to insist that all of the new research that suggest that the  fluorosilicic acid mined from the air  pollution scrubbers from chemical fertilizer plants and sold to us to put into our water supply may have some negative impact on our health is junk science. All of it is junk science as far as you are concerned. You insist only the research that says this pollutant it is completely safe is relevant.
