Drinking Water

Fluoride, a naturally occurring element, exists in combination with other elements as a fluoride compound and is found as a constituent of minerals in rocks and soil. When water passes over and through these soil and rock formations, it dissolves these compounds, resulting in small amounts of soluble fluoride being present in virtually all water sources. All water contains naturally occurring fluoride. Fluoride is also added to some public drinking water supplies, a process known as fluoridation. At the optimum level of 1 mg/l, fluoride reduces the occurrence of dental decay. Elevated levels of fluoride in drinking water can cause fluorosis, or mottling of teeth. High levels consumed over a long period can cause chronic toxicity. Extremely high levels, significantly above those found in water, can cause a acute toxicity. Tests by reputable, qualified laboratories can determine the concentration of fluoride in drinking water. If fluoride is present above a desirable level, options include using water treatment equipment to remove the fluoride or an alternative water source.
