What is the purpose of a sample site plan in water sampling?

The purpose of a sample site plan in water sampling is fundamentally to assure that samples are collected from active service connections. This is crucial because collecting samples from locations that are not currently in use may not accurately reflect the water quality being delivered to consumers. By creating a plan that targets active connections, operators can ensure that the water samples represent what customers are actually receiving, which is essential for monitoring water quality and ensuring compliance with health standards.

While toxicity testing, determining chemical profiles, and complying with federal regulations are all important aspects of water quality management, they do not directly relate to the specific purpose of a sample site plan. The plan focuses on ensuring the integrity and relevance of the samples collected, which ultimately supports ongoing assessments of water safety and quality.
