Harnett County officials discuss fluoride regulation and community health impacts

The Harnett County Board of Commissioners held a work session on April 1, 2025, focusing on the fluoridation process in the county's water supply. The discussion was prompted by ongoing public inquiries regarding fluoride levels and safety, particularly in light of recent court rulings and public health debates.

Commissioner Jaggers initiated the conversation, expressing the need for accurate information to address constituents' concerns about fluoride in the water. Tommy Burns provided a historical overview, noting that fluoride was first introduced into community water systems in 1945, with Harnett County beginning its fluoridation process in the 1950s. The county adheres to the Environmental Protection Agency's (EPA) recommended optimal level of 0.7 milligrams per liter, which is equivalent to three drops in a 55-gallon barrel of water.

Burns emphasized that fluoride serves as a public health additive, aimed at preventing dental decay without affecting overall water quality. He reassured the commissioners that the county's water treatment process includes regular monitoring and reporting of fluoride levels, which are consistently maintained within safe limits. The last annual report confirmed that the North Harnett Water Treatment Plant's average fluoride level remains at the recommended 0.7 mg/L, far below the EPA's maximum allowable levels.

The meeting also touched on recent controversies surrounding fluoride, including a court ruling in California that raised concerns about potential neurotoxicity in children under eight. This ruling has been appealed by the EPA, with support from various health organizations. Despite these discussions, Burns reiterated that fluoride's benefits for dental health remain significant, especially given the availability of fluoride in other products like toothpaste and mouthwash.

Commissioners expressed their support for maintaining fluoride in the water supply, highlighting its importance for children's dental health. They acknowledged the need for ongoing monitoring and communication with the public regarding fluoride levels and safety.

In conclusion, the work session underscored the county's commitment to public health through the continued use of fluoride in its water treatment process, while also addressing community concerns and regulatory standards. The commissioners plan to keep the public informed about any developments related to fluoride and its impact on health.
