The maximum number of pool users per 100 square feet of pool surface is typically

The maximum number of pool users per 100 square feet of pool surface is typically set to ensure both safety and comfort for all swimmers. This standard typically allows for approximately 25 users per 100 square feet of pool surface. This figure is derived from environmental health guidelines that consider factors such as the need for adequate space to swim freely, the potential for overcrowding, and the ability to maintain sanitary conditions in the water.

Regulatory guidance often suggests that this ratio supports safe aquatic activity and helps in managing the concentration of pathogens, as more users in a given space can lead to increased contamination. Higher numbers can compromise swimmer safety and the effectiveness of water treatment systems. Therefore, maintaining a ceiling of 25 users aligns with best practices in public health and recreational safety, making it the correct answer.
