It is disturbing that no mention of lead from fluoridation agents that are commercial grade. See AWWA Standard for Fluorosilicic Acid B703-06, latest issue, Foreword gives source and process evolving the liquid form most often used in fluoridation. Page 13 is an entire page of contaminants, heavy metals as arsenic, lead and more to radionuclides as uranium and radium 226-228, which degrade to 3 isotopes of lead.

The PubMed site reports Neurotoxicology, Sept. 2007, "Effects of fluoridation and disinfection agent combinations on lead leaching from leaded-brass parts", noting the chloramine and FSA resulted in lead spiking over 900ppb.
So this is actually 2 sources of lead added to our drinking water....

Then, consider processed foods and beverages made with this combination, and that it doesn't evaporate, but concentrates. Also, cooking with this water is even more adding to the burden in our diets.
