What is the primary risk of having unbalanced pool chemicals?

The primary risk of having unbalanced pool chemicals is the increased risk of waterborne illnesses. Pool water that is not properly balanced can create an environment conducive to the growth of harmful microorganisms, such as bacteria and viruses. For instance, low levels of chlorine can prevent effective sanitization, allowing pathogens to thrive. This can lead to outbreaks of illnesses like recreational water illness (RWI), which can affect swimmers and pool users.

Maintaining balanced pool chemicals, particularly pH, sanitizer levels, and alkalinity, is crucial to ensure a safe swimming environment. This includes regularly testing the water and adjusting chemical levels as needed to minimize health risks. The emphasis on preventing waterborne illnesses highlights the importance of proper chemical management in pool operations to protect the health of users.
