What is the purpose of a transmittal card in field sampling?

• A. To record weather data
• B. To schedule deliveries
• C. To document cost
• D. To carry jobsite information about the samples

Answer: (D)

Transmittal cards are used to carry jobsite information about the samples from the field to the lab, ensuring the lab has the context needed to identify, preserve, and analyze each specimen. They typically include details like project name or number, exact sample location or boring ID, sample IDs, depth, date and time collected, who collected it, preserving method, and the tests or analyses requested. This information helps maintain a clear chain of custody and prevents mix-ups by linking results back to the correct location and sampling conditions. Weather notes, delivery scheduling, or cost data aren’t the primary role of the card; those items are handled in separate logs or documents.
