What term describes a person located at a facility who monitors the daily operation at the facility and maintains contact with the remote operator?

• A. On-site operation
• B. On-site representative
• C. Public water system
• D. Air-gap separation

Answer: (B)

The term describes the person who is physically at the facility, watching daily operations and staying in touch with the remote operator. That person is the on-site representative—acting as the local contact responsible for monitoring day-to-day conditions, relaying information, and coordinating with the remote operator to keep operations running smoothly and safely. The other terms don’t fit: on-site operation refers to the activity itself, a public water system is the water system as an entity, and air-gap separation is a backflow prevention feature, not a person.
