Who is responsible for determining chlorine residuals in the distribution system?

Determining chlorine residuals in the distribution system is primarily the responsibility of the sampler collector. This role involves the systematic collection of water samples from specific points within the distribution system to assess water quality, including chlorine levels.

Monitoring chlorine residuals is crucial for ensuring safe and potable drinking water, and this task typically falls under the purview of personnel specifically trained in sampling techniques and water quality standards. The sampler collector uses appropriate methods and equipment to gather the samples, ensuring that they are representative of the water being distributed.

While the laboratory technician may analyze the samples for chlorine levels, they do not collect them from the field. Similarly, the supervisor oversees operations and ensures compliance with regulatory standards, but the actual sampling is a hands-on task assigned to the sampler collector. The maintenance crew focuses on physical infrastructure and repairs, rather than monitoring water quality metrics.

Thus, the sampler collector is the key figure in determining chlorine residuals in the distribution system due to their direct involvement in the sampling process.
