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

The primary purpose of conducting a sanitary survey in drinking water management is to identify sources, types, and amounts of pollution. This survey plays a critical role in ensuring the safety and quality of drinking water by assessing potential contamination sources within the water supply system. By identifying various pollutants, including microbial, chemical, and radiological contaminants, the survey helps water managers to understand the specific risks associated with the water source and to implement necessary control measures to protect public health.

Sanitary surveys include evaluating land use practices, assessing the proximity of potential pollution sources (like agricultural runoff or septic systems), and analyzing historical water quality data. With this comprehensive understanding, water utilities can prioritize interventions, improve water treatment processes, and ensure compliance with regulatory standards, ultimately safeguarding community health.

The other options, while relevant aspects of water management, do not capture the comprehensive purpose of a sanitary survey as effectively as identifying pollution sources and types.
