Before contaminating the Independence public water supply with sodium fluoride, please, dear public, investigate the precautions and dangers associated with this very questionable substance. A bit of research will reveal that sodium fluoride, a by-product of the munitions industry after World War II, is a known toxin to humans. Its use in the public water supply has actually been linked to an increase in hip fractures and osteoporosis, cancers, and genetic damage. Sodium fluoride inhibits the enzyme systems in the body and damages the immune system.
