Who shares responsibility for pool water quality monitoring?

• A. Pool treatment plant operator, bathing facility manager/lifeguard, and BE
• B. Public Health
• C. BE only
• D. Pool management only

Answer: (A)

Pool water quality monitoring is a shared effort among three key roles: the pool treatment plant operator, the bathing facility manager or lifeguard, and the Bacteriological Examiner (BE). The operator is responsible for running the treatment system, keeping disinfection and pH at proper levels, maintaining filtration, and documenting operational parameters. The facility manager or lifeguard ensures day-to-day operation alignment with safety rules, maintains records, and oversees staff and procedures that affect water quality. The BE handles sampling and laboratory analysis for microbial indicators, verifying that test results meet standards and providing an independent check on water safety. Public Health sets the regulations and oversees compliance, but the actual monitoring and verification involve all three groups working together. Choices that omit any of these roles miss a crucial piece of the monitoring process, which is why the combined responsibility is the best answer.
