What is the Maximum Contaminant Level (MCL) for chlorite in mg/L?

The Maximum Contaminant Level (MCL) for chlorite is indeed set at 1.0 mg/L. This standard is established to protect public health by regulating the concentration of contaminants in drinking water. Chlorite, a byproduct of the disinfection process involving chlorine dioxide, can pose health risks if consumed in high concentrations.

Setting the MCL at 1.0 mg/L ensures that water utilities maintain chlorite levels at safe concentrations, reducing the potential for adverse health effects while still allowing for effective disinfection of drinking water. This level reflects extensive research and the need for balancing public health protection with the practicalities of water treatment processes.
