How do levels of inorganic fluorides in Canadian lakes and rivers compare to the guidelines?
On average, the level of inorganic fluorides in fresh waters across Canada is 0.05 milligrams of inorganic fluoride per litre of water, or about half of the guideline value. Levels vary from lake to lake and depend, in part, on the presence of minerals containing inorganic fluorides in the immediate and surrounding area, water hardness and pH, and presence of bentonite clays and humic acid.
