El Toro Water District Started Receiving Fluoridated Water Supplies
November 19, 2007

The Metropolitan Water District of Southern California (Metropolitan) initiated fluoridation at its five treatment plants. The treatment plant that serves Orange County and El Toro Water District began fluoridation November 19, 2007. El Toro Water District receives 100% of its drinking water from Metropolitan. In line with the recommendations from the California Department of Public Health, as well as the U.S. Centers for Disease Control and Prevention, Metropolitan adjusted the natural fluoride level in the water, which ranges from 0.1 to 0.4 parts per million, to the optimal range for dental health of 0.7 to 0.8 parts per million. Fluoride levels in drinking water are limited under California state regulations at a maximum dosage of 2 parts per million. El Toro Water District will continue to provide water that meets the standards required by state and federal regulatory agencies.
