What is the primary function of sample stations?

The primary function of sample stations is to collect samples with minimized contamination. This is critical in water treatment processes since accurate testing is essential for assessing the quality of water and ensuring it meets safety standards. Sample stations are strategically designed to prevent outside contaminants from entering the samples, which helps guarantee that the results of any analysis reflect the true quality of the water.

By maintaining low contamination levels during sample collection, water treatment facilities can identify potential issues such as harmful bacteria, chemical pollutants, or other contaminants that may not be detected if sampling procedures introduce inaccuracies. This function supports the overall safety and reliability of the water supply, informing necessary treatment processes or public health responses.

The other options focus on functions that do not align directly with the role of sample stations. While treatment of contaminated water, monitoring of pump performance, and regulation of water distribution are all important aspects of water treatment operations, they are separate from the specific purpose of sample collection and quality assurance at sampling points.
