What is the MRDL for chlorine dioxide?

The maximum residual disinfectant level (MRDL) for chlorine dioxide is set at 0.8 mg/l. This regulatory guideline is crucial for ensuring the safety of drinking water while allowing for effective disinfection practices. Chlorine dioxide is used in water treatment primarily for its disinfectant properties, and maintaining the MRDL at 0.8 mg/l helps to minimize potential health risks associated with its use. This value reflects a balance between effective pathogen control and the need to limit exposure to chemicals in drinking water, thus safeguarding public health. The established MRDL is based on research and regulatory standards that evaluate the efficacy and safety of chlorine dioxide when used in water treatment processes.
