"...Testing found a maximum of 1.35 parts per million of fluoride in
drinking water. The maximum containment level allowed for fluoride is

The FDA recommends that fluoride added to bottled water must be added
in a concentration that varies from 0.8ppm and 1.7ppm, depending on
the annual average of maximum daily air temperatures.
Fluoride in bottled water
Figures according to bottled water producers:
Lauré Pristine Spring Water:
Level detected: Fluoride 0.1 mg/l
"In our Fluoridated water we ad 1 part per million Sodium Fluoride as
recommended by the American Dental Society."
"We add up to 1 mg of fluoride per liter of water. Therefore there is
up to 0.25mg of fluoride in one 255 mL (8.5 FL OZ) bottle of DANNON
Fluoride to Go."
