Eastern Municipal Water District announced that it increased it’s fluoride levels from the current level of 0.1 –0.4ppm up to 0.7-0.8ppm last October, as recommended by the California Department of Public Health. EMWD provides water to a large portion of Riverside County residents. They are increasing the fluoride levels in the Hemet/San Jacinto Valley summer of 2008. The American Dental Association is a strong supporter of community water fluoridation, and has stated that this is one of the 10 great public health achievements of the 20th century, and as a safe, beneficial and cost-effective way to prevent tooth decay in children and adults.
