Fluoride in Drinking Water

Currently, only water provided from the Elgin Area Primary Water Supply System is fluoridated.  Fluoride is not added at the Lake Huron Primary Water Supply System.  The City of London adds fluoride to Lake Huron water as it enters their distribution system to ensure that fluoride levels are maintained throughout the city.

Why is fluoride added to drinking water?

Fluoridation is a safe and cost-effective way to prevent tooth decay.  Depending on the water source, some municipalities may have naturally occurring levels of fluoride in their drinking water supply.  Others do not, so they adjust their fluoride levels to prevent tooth decay.

What type and quality of fluoride is used?

At the Elgin Area Primary Water Supply System, hydrofluosilicic acid (HFS) is the chemical used for fluoridation.

Any chemical used in the operation of the drinking water system that comes into contact with drinking water must meet applicable standards set by both the American Water Works Association (AWWA) and the American National Standards Institute (ANSI) safety criteria standard NSF/60: Drinking Water Treatment Chemicals - Health Effects.  NSF is responsible for the certification of water treatment chemicals to ensure that they do not contribute contaminants to drinking water that could cause adverse health effects.

How much fluoride is in the drinking water?

Ontario Regulation 169/03 (Ontario Drinking Water Quality Standards) under the Safe Drinking Water Act, 2002, establishes a maximum acceptable concentration of 1.50 mg/L for fluoride in drinking water.  It is further recommended that where fluoride is added to drinking water, the concentration should be adjusted to between 0.50 mg/L - 0.80 mg/L, which is the optimum level for the control of tooth decay. 

On average, the fluoride concentration of the treated drinking water from the Elgin Area Primary Water Supply System is maintained at 0.65 mg/L.
