The optimal level for fluoride is intended to prevent tooth decay and protect public health. In January 2011, the United States Department of Health and Human Services (HHS) and Center for Disease Control (CDC) issued a revised recommendation for the optimal level of fluoride in drinking water. Based on new research, HHS/CDC recommends a fluoride level of 0.7 mg/L as optimal for ensuring public health protection. In the past, HHS/CDC supported a fluoride level between 0.7 to 1.2 mg/L, as safe and effective in preventing tooth decay. The Town achieves the revised optimal fluoride level of 0.7 mg/L in its operations.
The issues regarding the benefits of adding fluoride to the drinking water have been debated for a number of years. The addition of fluoride to drinking water was identified by the CDC as one of the top ten health achievements of the 20th century. Most recently, in January 2017, CDC issued a statement on the evidence supporting the safety and effectiveness of community water fluoridation. You may view the CDC's statement at this CDC Statement of Support. You can also read additional CDC information regarding community water fluoridation at Water Fluoridation Guidelines & Recommendations. You can also read the US Surgeon General’s perspective on community water fluoridation at Surgeon General's Perspective.
The addition of fluoride to drinking water is a decision that is usually made at a community level. Fluoride is being added to the drinking water supply at the recommendation of HHS/CDC and the Virginia Department of Health (VDH). While the addition of fluoride serves no purpose in the water treatment process, it is added to achieve a public health goal.

aDDITIONAL FACTS REGARDING THE TOWN'S WATER SYSTEM
The Town uses sodium fluoride as an additive in the water system. The manufacturer of sodium fluoride is Solvay Fluorides, LLC. A Safety Data Sheet for the sodium fluoride is available at this link and includes contact and safety information.
The use of fluoride (a natural element) is a recommendation of the CDC and the VDH Office of Drinking Water. The application of fluoride in the Commonwealth of Virginia in low doses requires a Waterworks Class License administered through the Virginia Department of Professional and Occupational Regulation. In addition, individuals can supplement the addition of fluoride by using most over-the-counter toothpastes.
The Town targets a fluoride concentration of 0.7 mg/L in the water distribution system. The Town uses multiple water sources to provide water to its customers and conducts daily fluoride analyses. The 2021 annual average fluoride concentrations for those sources were:
- Water Treatment Plant: 0.73 mg/L
- Mountain View Well: 0.76 mg/L
- Forbes and Cornwell Well System: 0.73 mg/L
- Main Street and Village Case Well System: 0.72 mg/L
