The sampling points for required turbidity sampling in a community water system are located at the points where water enters the distribution system. This practice is important because monitoring turbidity at these points allows operators to assess the water quality before it reaches consumers. Turbidity is an indicator of water clarity and can reflect the presence of particulate matter that may harbor pathogens and other contaminants.

Sampling at the entry of the distribution system ensures that any issues with water quality are identified prior to distribution, enabling timely interventions. This is crucial for maintaining safe drinking water standards and protecting public health.

While sampling at the water source, chlorination point, or filtration system may provide useful information, these locations do not necessarily reflect the quality of the water that consumers will ultimately receive. In contrast, sampling at the distribution entry points gives a snapshot of the treated water's condition as it is about to enter the network that supplies the community.
