What is the purpose of conducting a sanitary survey in water management?

The purpose of conducting a sanitary survey in water management is to identify sources and amounts of pollutants. This evaluation is critical for protecting public health and ensuring water safety. Through a sanitary survey, various potential contamination sources, such as agricultural runoff, industrial discharges, and wastewater, are assessed. Understanding these sources allows water management teams to implement appropriate interventions and regulatory measures to mitigate risks. Such proactive analysis is essential in developing effective strategies for water quality monitoring and improving overall water management practices.

The other options relate to different aspects of water quality monitoring but do not encompass the primary aim of a sanitary survey, which is focused on identifying pollution sources that may affect water safety.
