What is the maximum recommended chlorine level before it is safe to swim?

The maximum recommended chlorine level for safe swimming is generally around 5 ppm (parts per million). At this concentration, chlorine is effective in disinfecting the pool water, helping to eliminate harmful pathogens while still being safe for swimmers. Concentrations above this level can cause skin and eye irritation, discomfort, and adverse reactions in sensitive individuals.

Maintaining chlorine levels within the recommended range, particularly around 3 to 5 ppm, supports both swimmer safety and effective sanitation, making it crucial to monitor and adjust levels accordingly. Levels higher than 5 ppm may not only be uncomfortable for swimmers but could also indicate that the water requires balancing or additional treatment to stabilize chemical levels. This recommendation aligns with public health guidelines that emphasize both water quality and swimmer safety in pool management practices.
