At levels over 1.5 mg/L, it can directly impact human health so must be removed to ensure a safe water supply. Nonetheless, as the negative health impacts only occur over the long term and because they are time consuming to establish, Fluoride Removal processes are more suited to the stabilisation and recovery phases.
