Flouridating water London free sex cams
Water fluoridation is simply a process in which naturally occurring fluoride levels in drinking water are adjusted to an optimal level recommended by the U. Department of Health and Human Services of 0.7 mg/L (parts per million) for the prevention of tooth decay.
SJW’s own sources of supply from its wells and surface water from the Santa Cruz Mountains contain low levels of naturally occurring fluoride.
To reach the Santa Clara Valley Water District Fluoride Hotline, please call (408) 630-2020.
When you enter your location into the tool below, you will receive a water fluoridation number that is calculated based on a six-month running average of the fluoride concentration levels collected at the sample station nearest you.
US Public Health Service recommends water has fluoride concentration levels of 0.7 milligrams per liter.
In areas with fluoride concentration levels below 0.6 milligrams per liter, the American Academy of Pediatrics and the American Dental Association recommend that children between the ages of 6 months and 16, who are at risk for tooth decay, be prescribed a daily fluoride supplement.
We are continuing to evaluate water samples to determine fluoride levels and will provide updated information as it becomes available.
The Santa Clara Valley Water District is anticipated to deliver fluoridated water from all three of its water treatment facilities by late 2020.

The Santa Clara Valley Water District began delivering fluoridated water to SJW in 2016.
Some customers throughout our service area are already receiving fluoridated water.
As required and to comply with all drinking water laws and regulations, SJW must then fluoridate our water supply if the necessary outside funding is provided.
