We have temporarily suspended fluoridation pending review of a fluoride overfeed incident at our water treatment plant on Thursday, February 2, 2017.
In accordance with recommendations of the US Centers for Disease Control and Prevention (CDC), American Dental Association (ADA), and other public health-related organizations, OWASA adds fluoride to drinking water to help prevent tooth decay. The level of fluoride in our water is about 0.7 of one part per million. (One part per million is like a penny is $10,000.)
Why does OWASA fluoridate its drinking water?
To help prevent tooth decay, as recommended by the CDC, ADA, NC Division of Public Health, NC Public Water Supply Section, and other public health-related organizations. The ADA says that "fluoridation is a safe and effective means of preventing tooth decay. It has been cited by the CDC as one of 10 great public health achievements of the 20th century. Studies show that fluoridation can prevent between 15–40 percent of decay."
Fluoride protects teeth from decay by strengthening tooth enamel and making it more resistant to acids produced by bacteria that are naturally present in our mouths.
What is the optimum level of fluoride in drinking water?
In April 2015, the US Department of Health and Human Services (HHS) finalized its guideline for the optimum fluoride level as 0.7 of one part per million based on a review of scientific research. The US Environmental Protection Agency (EPA) will review this recommendation before deciding whether to change the regulatory standard. We will continue to monitor water treatment research and will consider such information and the guidance of regulatory authorities in making decisions on treating our community's water.
What is the fluoride level in our water?
In 2015, the level of fluoride in our drinking water was 0.70 of one part per million (ppm). (One part per million is like a penny is $10,000.)
