Which of the following is not listed as an inspection interval in the guidelines?

• A. Biannually
• B. Quarterly
• C. Monthly
• D. Annually

Answer: (A)

The main idea is recognizing the standard inspection cadences used in ITM guidelines for water-based systems. Those guidelines typically specify routine inspections on a monthly basis, quarterly basis, and annually. A six-month interval—biannually—is not part of those standard cadences, so it isn’t listed. Monthly inspections help catch small issues early, quarterly inspections provide a more thorough check, and annual inspections cover comprehensive testing and verification. If a six-month interval is needed, guidelines usually don’t list it as a fixed cadence and would instead refer to the standard intervals or to event-driven/as-required inspections.
