Which role is responsible for overseeing sampling activities in the field?

• A. Assistant Sampler
• B. Operations Manager
• C. Quality Assurance
• D. R&S Element Team Leader

Answer: (D)

The main idea here is who is on-site to direct the sampling work. In field operations, the person who leads the team performing the sampling is responsible for making sure the plan is carried out correctly, safety procedures are followed, equipment is used properly, and any issues are resolved in real-time. The R&S Element Team Leader fits this role because they oversee the reconnaissance and sampling element, coordinate personnel, ensure adherence to sampling procedures, manage on-site logistics, and maintain proper documentation and communication with higher levels of the team. An assistant sampler handles hands-on tasks under supervision and doesn’t have the authority to oversee the entire operation. Quality Assurance focuses on evaluating results and process quality rather than directing field activities day-to-day. An Operations Manager has broader, higher-level responsibilities and may not be on-site to guide the actual sampling work.
