What is the acceptable range for chlorine levels in a swimming pool to ensure safe swimming?

The acceptable range for chlorine levels in a swimming pool to ensure safe swimming is typically between 1-3 parts per million (ppm). This range is essential for effective disinfection and helps maintain a safe environment for swimmers. Chlorine is used to kill harmful bacteria and other pathogens, ensuring that the water is sanitized and safe for human use.

If the chlorine levels are too low, there is an increased risk of waterborne illnesses due to insufficient disinfection. On the other hand, levels that are too high can lead to skin and eye irritation for swimmers, as well as a noticeable chlorine smell, which can deter people from enjoying the pool.

Maintaining chlorine levels within the 1-3 ppm range strikes a balance between effective sanitation and comfort for users, making it crucial for pool operators to regularly monitor and adjust chlorine levels as needed.
