Which role is responsible for identifying required sampling supplies?

• A. Quality Assurance
• B. Site Engineer
• C. Sample Collector
• D. Health and Safety Officer

Answer: (C)

In field sampling, the person who actually collects the samples is the one who identifies what supplies are needed. They know the exact method being used and the matrix being sampled, so they can specify the right containers, preservatives, labeling, forms, any field blank or filtration tools, and the appropriate PPE. By determining these requirements beforehand, they ensure everything necessary is on hand, containers are appropriate for preserving sample integrity, and nothing is missed that could compromise results or violate procedures.

Quality Assurance centers on checking that processes and results meet standards, but not the day-to-day listing of field supplies. The Site Engineer focuses on site operations and infrastructure rather than the specific sampling materials. The Health and Safety Officer concentrates on safety protocols and protective equipment, not the complete set of sampling consumables.
