Article: Fluoride Removal General Mineral Analysis And Design Data Bulletin
Dissolved fluoride usually occurs in water supplies as compounds of calcium-fluoridephosphate. Well waters generally have higher fluoride concentrations than surface waters due to the fact that they have greater exposure to fluoride bearing minerals. The USEPA has established regional maximum contaminant levels (MCL) for fluoride that are based on the probable daily ingestion of water. The optimum fluoride level established by the U.S. Public Health Service is one half of the MCL.
Due to the natural affinity of fluoride ions for calcium, there is a complex interaction between ingested fluoride and skeletal components. Dental fluorosis is recognized as a direct result of ingestion of water with fluoride content exceeding the MCL by children up to twelve years old. It can vary from mild discoloration of the tooth enamel to severe embrittlement of the tooth structure. Fluoride toxicosis can cause serious bone deterioration.
Fluoride can be efficiently removed from potable water to levels below the EPA and Health Department standards, when complete and accurate water quality data is available.
