Fluoride pollution from various industrial emissions can also contaminate water supplies. In a few areas of the United States, fluoride concentrations in water are much higher than normal, mostly from natural sources. In 1986, EPA established a maximum allowable concentration for fluoride in drinking water of 4 milligrams per liter (mg/L).
That decision does not necessarily mean fluoride must be removed from U.S. drinking water—the EPA can choose to address the situation in a number of ways, including releasing a public notice ...
In Bogota, the average drinking water fluoride concentration is 0.08 ppm. Medellin is the only city which preserves an annual oral health prevention programme based on education and fluoridated mouth rinses in public schools since 1981, and its drinking water contains an average Fluoride concentration of 0.05 ppm. Cartagena is located in the ...

Fluoridated water contains fluoride at a level that is effective for preventing cavities; this can occur naturally or by adding fluoride. [2]
Water fluoridation is not mandatory, and while there is a recommended fluoride concentration in drinking water (0.7 milligrams per liter) from the CDC, that level is not an enforceable standard.

Indoor tap water is distributed through indoor plumbing, which has been around since antiquity but was available to very few people until the second half of the 19th century when it began to spread in popularity in what are now developed countries.
