- At 0.7 mg/L (water fluoridation level), helps prevent tooth decay
- Possible thyroid effects at high chronic exposure
Health risk severity: Moderate. Governed by the National Primary Drinking Water Regulations.
How Fluoride Gets Into Drinking Water
- Intentional water fluoridation (0.7 mg/L target, beneficial)
- Natural deposits in certain rock formations
- Industrial discharge (aluminum, fertilizer production)
- Naturally elevated in some groundwater (especially arid regions)
