How can an inspector verify the legitimacy of the truck’s meter readings for water added during transit?

• A. Compare meter readings with the plant's water added records only.
• B. Compare with batch ticket data and with the plant's recorded water added, and verify calibration of the meter.
• C. Rely on the truck's meter readings without cross-check.
• D. Record readings and proceed without verification.

Answer: (B)

The main idea is to verify water added during transit by using multiple independent sources and ensuring the measuring device is accurate. The best approach is to cross-check the truck’s meter readings against batch ticket data and the plant’s recorded water added, and to confirm the meter is properly calibrated.

Why this is the strongest approach: batch tickets document the intended water amounts for each batch, while the plant’s records show what was actually added at the plant. Comparing both with what the truck’s meter shows creates a checks-and-balances system that can reveal discrepancies, tampering, or timing issues. Verifying the meter’s calibration ensures the instrument itself is measuring correctly and not providing biased or erroneous readings. Together, these steps provide reliable, traceable evidence of how much water was added.

Why the other options fit less well: relying only on the truck’s meter readings lacks independent verification and can miss errors or manipulation; depending solely on the plant’s records ignores what occurred during transit and any differences between plant additions and what the truck records; recording readings and proceeding without verification leaves potential inaccuracies unaddressed and untraceable.
