Frequently Asked Questions

Is my water fluoridated?

No, Firgrove does not fluoridate its own ground water supply.  Less than 15% of the water we deliver to our customers is purchased from Tacoma Public Utilities. However, Tacoma’s water supply is fluoridated. The recommended dosage for purveyors that fluoridate the water supply is 0.7 parts per million. Firgrove recommends following your pediatrician’s or dentist’s recommendations for fluoride treatment. If you have any questions or comments, please contact Steve Sacksteder, Water Quality Technician @253-286-2847 or
