What is the typical acceptable level of chlorine in drinking water?

• A. 0.2 to 0.5 mg/L
• B. 1.0 to 4.0 mg/L
• C. 0.5 to 1.0 mg/L
• D. 5.0 to 10.0 mg/L

Answer: (B)

The typical acceptable level of chlorine in drinking water is between 1.0 to 4.0 mg/L. This concentration range is effective for disinfection purposes, ensuring that harmful pathogens are eliminated while being low enough to avoid unpleasant tastes and odors. Chlorine is a common disinfectant that protects public health by reducing the risk of waterborne diseases. Levels within this range are recommended by various health organizations, including the Environmental Protection Agency (EPA), to ensure that water is safe for human consumption while maintaining adequate residual levels to prevent recontamination as water flows through distribution systems. This balance is crucial in water treatment practices, which aim to provide safe drinking water to the public.
