What is the recommended range for chlorine levels in swimming pools?

• A. 0-1 ppm
• B. 2-4 ppm
• C. 5-8 ppm
• D. 1-2 ppm

Answer: (B)

The recommended range for chlorine levels in swimming pools is 2-4 ppm (parts per million). Maintaining chlorine levels within this range is important for ensuring effective sanitation, which keeps the pool water safe and clean for swimmers. Chlorine serves as a disinfectant that helps kill harmful bacteria, viruses, and other microorganisms that can cause illness. Levels that are too low, such as those in the 0-1 ppm range, may not provide adequate sanitation, leading to a higher risk of waterborne illnesses. Conversely, excessively high levels, such as those exceeding 5-8 ppm, can cause discomfort for swimmers, such as skin and eye irritation, and may lead to an unpleasant chemical smell, diminishing the overall swimming experience. Thus, by keeping chlorine concentrations within the 2-4 ppm range, pool operators can effectively balance safety and swimmer comfort, ensuring a healthy pool environment.
