How much flouride is there in the water?
There are about 0.1 parts per million of naturally occuring fluoride in our groundwater as it is pumped from our wells. By vote of the Townspeople, Wellesley has required the Wellesley DPW to add an additional 0.9 parts per million as part of the treatment process. Therefore your tap water has 1.0 parts per million of fluoride.
