Increasing the aluminum, calcium, and magnesium levels in the diet or in the gut contents decreases absorption because fluoride forms relatively insoluble salts with these metals. Water hardness does not affect fluoride bioavailability in a toxicologically significant manner. Aluminum is the third most common element in the earth's crust and is present in soil, water and air.

Aluminum's physical and chemical properties make it ideal for a variety of uses in food, drugs, consumer products, and water … Aluminum in water seldom is a concern for municipal water systems. Entry into drinking water unlikely from crop applications (clay binding); however, may persist in water for several days if directly applied to water. SAN DIEGO (Reuters Health) - Adding support to a controversial theory linking aluminum with Alzheimer's disease, new research indicates the disease is more common in regions of northwest Italy where levels of aluminum in drinking water are highest. Haloacetic acids (HAA5) n/a 6: 0.060: Increased risk of cancer. Excessive aluminum intake may cause neuromuscular effects, although drinking water aluminum intake by humans is minor compared with intake from other sources. According to the CDC, aluminum levels generally do not exceed 0.1 PPM during water treatment, though several cities have reported concentrations as high as 0.4–1 PPM in their drinking water. The aluminum content of city water supplies is variable, but on occasion, concentrations as high as 0.4–1 mg/L have been reported in drinking water. Aluminum is an extremely abundant metal in the earth’s crust. It has been known to cause deposits in cooling systems and contributes to boiler scale. The defense made by agencies promoting water fluoridation, such as the US Centers for Disease Control, to the lack of such studies, is that when the silicofluoride complex is diluted into water, it dissociates into free fluoride ions or other fluoride compounds (e.g. Semantic Scholar is a free, AI-powered research tool for scientific literature, based at the Allen Institute for AI.

Health Canada technical document related to the quality of drinking water in Canada Drinking water officers are responsible for issuing operating permits, and will work with water suppliers to help them achieve compliance with the legislation and the conditions on their permits. Aluminum is a metal widely distributed in nature. Non‐health‐based effects in drinking water, such as post‐precipitation and pipe scales in the distribution system, are more of a problem than health‐based concentrations. The metal is used for many purposes: in the production of construction materials, vehicles, aircraft, electronics, pharmaceuticals and personal care products; as food additives; and as components of food packaging materials. Sources of Contaminant in Drinking Water; Bromate: zero: 0.010: Increased risk of cancer. This includes the brain, since aluminum passes the blood-brain barrier and is also distributed to the fetus in pregnant women. Drinking water containing aluminium was considered to be one of the main sources of Al intake into human body. 2. Overview.
