Water GlassFluoride has been added to U.S. drinking water supplies since 1945. Of the 50 largest cities in the U.S., 43 fluoridate their drinking water. In December 2007, the Metropolitan Water District of Southern California joined a majority of the nation's public water supplies in adding fluoride to drinking water in order to prevent tooth decay. Metropolitan is the primary supplier of imported water to Laguna Beach and many Southland residents. 

In line with recommendations from the CDPH, as well as the U.S. Centers for Disease Control and Prevention, Metropolitan adjusted the natural fluoride level in imported treated water from the Colorado River and State Water Project water to the optimal range for dental health of 0.6 to 1.2 parts per million. Fluoride levels in drinking water are limited under California state regulations at a maximum dosage of 2 parts per million.

Is it harmful to my health?
Hundreds of studies have looked at whether there is a link between fluoride and cancer, as well as adverse effects on the immune system, kidneys, digestive, and reproductive system. In reviewing the body of evi­dence, the American Dental Association concluded that “the overwhelming...evidence indicates that fluoridation of community water supplies is both safe and effective.”

What if I do not want to drink fluoridated water?
Reverse osmosis or distillation home devices remove significant amounts of both naturally occurring fluoride and fluoride added through fluoridation. The National Sanitation Foundation (NSF) certifies certain reverse osmosis home treatment devices and distil­lation units for the reduction of fluoride. For a list of NSF certified devices, visit www.nsf.org/certified/DWTU. It is important to regularly maintain these devices for optimum effectiveness.
