What can excessive chlorine levels in pool water cause?

Excessive chlorine levels in pool water can lead to increased skin irritation for swimmers. Chlorine is commonly used to disinfect pools and control harmful pathogens, but when its concentration is too high, it can react with organic materials in the water, forming chloramines. These chloramines are responsible for the strong chlorine smell often associated with swimming pools and can cause skin and eye irritation for swimmers.

While maintaining a balanced level of chlorine is essential for effective disinfection and swimmer comfort, an overabundance can disrupt this balance. Skin irritation may manifest as rashes, dryness, or burning sensations, making it uncomfortable for individuals who use the pool. Therefore, monitoring and regulating chlorine levels is crucial in ensuring the health and safety of pool users.

Other choices, while related to pool chemistry, do not accurately reflect the outcomes associated with excessive chlorine levels. Improved water clarity and swimmer comfort typically result from properly balanced chemical levels, not from an excess of chlorine. Similarly, disinfection efficiency is compromised if chlorine levels are too low or improperly balanced, but not from excessive levels.
