What is the acceptable limit of turbidity in normal pools measured in NTU?

The acceptable limit of turbidity in normal pools is generally recognized at 0.5 NTU (Nephelometric Turbidity Units). Maintaining turbidity at or below this level is crucial for ensuring water clarity and safety, as higher turbidity can indicate the presence of harmful microorganisms or contaminants that affect both the aesthetics and the health standards of pool water.

At 0.5 NTU, pool owners can be more confident in the effectiveness of the disinfection processes and the overall water quality, providing a safer swimming environment for users. Clearer water also enhances the visibility and enjoyment of swimming activities, making adherence to this limit particularly important in public health practices.

While other limits mentioned might be considered for different contexts, 0.5 NTU is the accepted value for normal pool operation, reflecting best practices in aquatic facility management.
