I assume you are a resident of Waterloo where the water is currently being flouridated. Have you tested the water in Kitchener (currently not flouridated) to see if the same heavy metal levels exist? Just because those elemets are present in the water system does not necessarily mean that they are the result of the flouride additive. Ground water often has traces of these and many other metals. Correlation does not establish causation.
