Because the city's water is of such high purity, nothing is added to the water except for small amounts of chlorine; this ensures that the water stays pure as it moves through the system. Fluoride is not added to city water. Fluoride occurs in trace amounts naturally at a level of .18 mg/L (fluoride containment level begins at 4.0 mg/L).
The city's water hardness has been measured at 171 mg/L, which is in the range of hard water.
