How frequently should the fluoride concentration of treated water be measured?

• A. Weekly
• B. Every day
• C. Monthly
• D. Every other day

Answer: (B)

Fluoride concentration in treated water should be measured every day to ensure that it remains within the established safety and efficacy standards. Daily monitoring is essential because fluoride levels are crucial for preventing dental caries while also posing potential health risks if levels become excessive. This frequency allows for immediate corrective action to be taken if the concentration strays from the optimal range, ensuring both public health and compliance with water quality regulations. Adequate fluoride levels help in promoting dental health, particularly in communities that rely on treated water for drinking and eating. Maintaining a daily measurement schedule guarantees that water treatment facilities can respond promptly to any fluctuations in fluoride concentration.
