Which of the following is NOT a common health hazard associated with floods?

The selection of clean drinking water as the option that is not a common health hazard associated with floods is accurate because, during and after floods, access to clean drinking water often becomes compromised. Floodwaters can contaminate public and private water supplies with pathogens, chemicals, and debris, leading to serious health risks.

In contrast, the other options represent recognized health hazards that can arise during flood events. Disruption of public utilities can diminish essential services such as electricity and sanitation, increasing health risks. Electrocution is a significant danger as live electrical wires can come into contact with floodwaters, creating a risk for anyone in the vicinity. Mold and mildew growth can occur in damp, flooded conditions, leading to respiratory issues and other health complications.

Therefore, the presence of contaminants in water supply during floods illustrates why clean drinking water cannot be considered a health hazard but instead a critical concern for public health in the aftermath of flooding.
