The state of California requires water agencies serving more than 10,000 customers fluoridate their drinking water supplies if outside funding is provided. At this time, the City of San Diego has not received sufficient outside funding to pay for a fluoridation system that would cover its entire distribution system. However, the City does measure and report a small amount of fluoride in our water supply that occurs naturally due to erosion.

In December 2007, the City of San Diego began receiving fluoridated treated water from the Metropolitan Water District of Southern California through the San Diego County Water Authority. The City water supply currently consists of approximately 9 percent of imported treated water. Because this is only a small portion of the City water supply, not all areas of the City receive fluoridated water. In addition, due to seasonal demands and operational changes, fluoride levels will vary throughout the system over time.
