Which factor is not typically considered when assessing pool water quality?

When assessing pool water quality, factors such as pH level, free chlorine level, and water temperature play crucial roles in ensuring safe and healthy swimming conditions.

The pH level is essential because it indicates how acidic or alkaline the water is, affecting both the effectiveness of chlorine as a sanitizer and the comfort of swimmers. Free chlorine level is critical as it measures the amount of available chlorine that can disinfect the water and remove harmful pathogens. Water temperature can influence swimmer comfort and the effectiveness of certain chemicals, as well as the activity level of bacteria and algae.

In contrast, while pool liner color may affect the aesthetic appeal of the pool, it does not impact the water's chemical balance or its safety for swimming. Therefore, it is not a relevant factor in assessing the actual quality of the water itself.
