Which is NOT a core element of a field sanitary survey for a temporary camp?

• A. Water source and treatment
• B. Handwashing facilities
• C. Vector breeding sites
• D. Power grid resilience

Answer: (D)

In a field sanitary survey for a temporary camp, the focus is on conditions that directly affect health risks: safe drinking water and whether treatment is adequate, the availability and condition of handwashing facilities to promote hygiene, and the presence of breeding sites for vectors that can transmit disease. Power grid resilience, while important for overall operations, does not directly determine water quality, sanitation facilities, or vector control, so it isn’t a core part of the sanitary assessment. Thus, power grid resilience is the item that does not belong.
