What I heard from former water treatment workers is that the drums that are labeled fluoride, comes from China. Can we get a virus from that? If fluorosalisic acid is present, that probably kills all pathogens. It would be extremely easy, IMHO and knowledge to add anything to the water system when they have direct access. People forget about lead in baby toys and toxic melamine in baby formulas from China. I realized a long time ago that municipal water is extremely toxic. My symptoms cleared up when going to the pure source. It cheated a lot of physicians out of thousands of dollars in tests and office fees.
