§64-3-8. Public Water System Fluoridation.
8.1. A public water system which artificially adjusts fluoride levels shall strive to maintain those levels between 0.6 milligrams per liter and 0.8 milligrams per liter. The optimum target concentration for artificially adjusted fluoride is 0.7 milligrams per liter. If the drinking water of a public water system is found to be outside of the 0.6 to 0.8 milligrams per liter range, the public water system shall make any treatment or operational changes necessary to return the fluoride level to within the range within 24 hours of receiving the analytical result unless doing so is impracticable, in which case, the correction shall be made as soon as possible. A public water system shall identify in its annual report to the bureau the date and time of each instance where the fluoride levels were found to be outside the target range and how long it took to implement responsive adjustments.
8.2. The drinking water of artificially adjusted fluoridated or defluoridated public water systems shall be monitored once each day for fluoride concentration. Records of the monitoring shall be maintained in accordance with sections 9 and 10 of this rule.
8.3. At least once a month, any public water system that artificially adjusts the fluoride concentrations shall submit a sample of drinking water to the Commissioner or to a certified laboratory for fluoride analysis.
8.4. A public water system may adjust fluoride concentration levels or dosage rates in accordance with subsection 8.1. without the prior written approval of the commissioner.
8.5. A public water system may not modify the chemical composition or additives for water fluoridation, or discontinue fluoridation of drinking water, without the prior written approval of the commissioner.
8.5.1 Upon written request, the commissioner may authorize a modification to the chemical composition or additives for water fluoridation, or the discontinuance of fluoridation of drinking water.
8.5.2 In the event the commissioner approves a modification or discontinuance pursuant to this subsection, the commissioner may also impose additional monitoring requirements.
