The calculation of the amount of fluoride to be added to water to obtain the optimal fluoride concentration is a mathematical formula which takes into account the concentration of the fluoridating agent and the volume of the water to be treated. The basic formula is then adjusted to allow for existing background fluoride levels in order to provide that the fluoride concentration of the water is in line with the statutory requirement.
