Which option is NOT a correct labeling or parking requirement for water trucks carrying aircraft potable water?

• A. Trucks must be clearly marked Potable Water
• B. Trucks must be parked in a Restricted Area
• C. Trucks must be clearly marked Non Potable Water
• D. Trucks must be sampled Quarterly

Answer: (C)

Potable water must be handled with clear identification and controlled access to protect water quality. A truck delivering potable water should be clearly labeled Potable Water so anyone handling it knows the water is safe for drinking and to prevent cross-contamination. Parking in a Restricted Area helps ensure that only authorized personnel can access the water, reducing contamination risk. Water quality is monitored regularly, and quarterly sampling is a typical part of verifying that standards are met. Labeling a potable-water truck as Non Potable Water would be misleading and could lead to improper handling or use, compromising safety and compliance. So the statement about labeling as Non Potable Water is not correct.
