Who identifies what is needed to collect samples?

• A. Field Supervisor
• B. Sample Collector
• C. Lab Technician
• D. Safety Officer

Answer: (B)

Identifying what is needed to collect samples comes from the person who actually performs the sampling in the field. The sample collector translates the sampling plan into hands-on reality, choosing and gathering the right containers, preservatives, labeling materials, chain-of-custody forms, PPE, sampling devices, and appropriate transport packaging. This ensures samples stay representative and uncontaminated from collection through transport. A field supervisor manages safety and overall adherence to the plan but typically does not specify the exact field supplies. A lab technician focuses on how the samples will be analyzed, not the field equipment or supplies. A safety officer concentrates on hazards and protective measures rather than the specifics of sampling materials. So, the sample collector is the best fit for identifying what is needed to collect samples.
