Why is fluoride classified as an Inorganic Primary Contaminant?

Fluoride is classified as an inorganic primary contaminant primarily due to its potential harmful effects when present in high concentrations. Ingesting excessive amounts of fluoride can lead to a condition called fluorosis, which negatively impacts bone and tooth health. While fluoride does have beneficial properties when used in appropriate amounts—such as promoting tooth enamel strength and helping prevent dental decay—this practice is carefully monitored because high levels can cause serious health issues, including damage to the skeletal system.

The classification as an inorganic primary contaminant underscores the importance of regulating fluoride levels in drinking water to prevent adverse health outcomes. Public health guidelines aim to balance the benefits of fluoride in preventing cavities with the risks of overexposure, which is why monitoring is essential.
