What is one of the risks of not properly managing pool chemicals?

Not properly managing pool chemicals poses a significant risk of potential harm to swimmers. This can occur due to imbalanced water chemistry that may lead to unsafe swimming conditions. For instance, incorrect levels of chlorine or pH can cause skin irritations, respiratory problems, or eye irritation. Furthermore, high levels of certain chemicals can increase the toxicity of the water, leading to serious health issues for those who swim in it.

When chemicals are not managed properly, it can also result in the proliferation of harmful bacteria or algae, which can contribute to illness. Therefore, maintaining proper levels and managing pool chemicals is critical to ensuring a safe and healthy swimming environment for everyone.

The other options, such as improved water clarity or attraction of wildlife, do not reflect the serious health implications associated with mismanaged pool chemicals. Similarly, the lifespan of pool materials could be negatively affected rather than being extended, as improper chemical management can lead to corrosion or damage of pool surfaces and equipment.
