What is the purpose of a sanitary survey?

• A. To identify water quality parameters only.
• B. To document consumer complaints.
• C. To determine the best capital improvement plan.
• D. To evaluate whether the water system can produce and distribute safe water and identify deficiencies for correction.

Answer: (D)

A sanitary survey is an on-site assessment of a water system to ensure it can produce and distribute safe drinking water and to identify deficiencies that must be corrected. It examines the system’s source, treatment, storage, and distribution, along with how the system is operated and maintained, the qualifications of personnel, records, and management practices. The focus is on whether the overall operation can consistently deliver safe water, not just on measuring specific water quality parameters. By pinpointing deficiencies—such as inadequate disinfection, poor maintenance, weak cross-connection controls, or gaps in emergency planning—the survey guides corrective actions to protect public health. While related activities like monitoring water quality, handling complaints, or planning improvements may occur, they aren’t the primary purpose of the survey itself.
