What is the purpose of a watershed sanitary survey?

A watershed sanitary survey is primarily conducted to evaluate potential sources of contamination in the watershed and to assess the adequacy of the water supply. This survey is crucial for identifying risks that could impact the quality and availability of water for public consumption, ensuring that any potential contaminants—whether from agricultural, industrial, or domestic sources—are identified and managed appropriately. By understanding these factors, water treatment facilities can implement necessary measures to protect public health.

While improving aesthetic quality, regulating temperature, and maintaining recreational activities are all important aspects of watershed management, they are not the primary focus of a sanitary survey. The core objective of this survey is to protect the drinking water source and ensure it is safe for use, making the evaluation of contamination risks and water supply vital elements of the overall water quality management strategy.
