How can cross-contamination be eliminated with the water distribution truck?

Clearly marking the trucks as either potable or non-potable directly addresses the issue of cross-contamination in the water distribution system. By using distinct labels or colors to differentiate the types of water being transported, personnel are visually reminded of the specific usage of each truck. This serves as a critical safety measure to prevent accidental mixing of potable and non-potable water, which could have serious health implications.

The proper labeling enables operators and anyone involved in the handling of the trucks to quickly identify which vehicle is suited for drinking water and which is for other purposes. This awareness is essential in maintaining the integrity of the water distributed and ensures compliance with health regulations and safety standards.

While other options may contribute to operational safety or provide helpful information, labeling the trucks is the most direct and effective method for preventing cross-contamination.
