What range of fluoride does the state recommend that a system maintain?

The recommended range of fluoride for a water system to maintain is 0.7 to 1.3 mg/L. This range aligns with public health guidelines aimed at optimizing dental health. Fluoride is added to drinking water to help reduce the incidence of dental caries (cavities) in the population.

In this range, the concentration is sufficient to deliver the health benefits associated with fluoride without posing significant health risks. Levels below 0.7 mg/L may not provide adequate dental protection, while levels above 1.3 mg/L could potentially lead to dental fluorosis, a condition that affects the appearance of teeth.

Maintaining fluoride within this recommended range helps ensure that drinking water can support community health effectively.
