What is the typical acceptable limit of chlorine in potable water?

The typical acceptable limit of chlorine in potable water is 4 mg/L. This standard is established based on both regulatory guidelines and safety considerations. Chlorine is commonly used as a disinfectant in water treatment to kill pathogens and ensure the microbiological safety of drinking water. However, excessive chlorine can pose health risks, such as respiratory problems and irritation to the skin and eyes.

The limit of 4 mg/L balances the need for effective disinfection while minimizing any potential adverse health effects from chlorine exposure. This concentration is generally considered safe for human consumption and is widely accepted in public health standards. Understanding this limit is crucial for water treatment professionals to maintain safe drinking water standards in their distribution systems.
