Fluoridation in the Otay Water District
Drinking water in Otay Water District's service area is fluoridated. The Otay Water District does not add fluoride to the water supply. Rather, the District purchases treated drinking water from area water wholesalers. Water wholesalers supplement the existing fluoride in the water supply raising it to approximately 0.8 parts per million (ppm), the level recommended by public health experts for optimal dental health.
Due to the blending of waters within the regional water distribution network, fluoride levels have varied by region and time of year. As of January, 2011, all water wholesalers in San Diego County added fluoride.This action resulted in less variation in fluoride levels throughout the regional water distribution network.
Some fluoride is already present in our water supply. Most water in San Diego County comes from the Colorado River or the Sierra snow pack. As water passes over the surface of the earth, it picks up fluoride through the natural erosion process. Fluoride is present in the water supply at approximately 0.2 ppm, with a range of 0.1 to 0.4 ppm. After January, 2011, all water in the region's distribution network will be consistently 0.6 to 0.9 ppm.
We encourage customers taking or who are considering taking fluoride supplements to consult their medical or dental health care professional.
