Epidemiology Week 33

Flood Waters or Standing Waters

Health Risks

Flood waters and standing waters pose various risks, including infectious diseases, chemical hazards, and injuries.


Diarrheal Diseases

Eating or drinking anything contaminated by flood water can cause diarrheal disease.


Chemical Hazards

Be aware of potential chemical hazards during floods. Flood waters may have moved hazardous chemical containers of solvents or other industrial chemicals from their normal storage places.



Flood water poses drowning risks for everyone, regardless of their ability to swim. Swiftly moving shallow water can be deadly, and even shallow standing water can be dangerous for small children.

Vehicles do not provide adequate protection from flood waters. They can be swept away or may stall in moving water.


Electrical Hazards

Avoid downed power lines.


Flood waters may contain sharp objects, such as glass or metal fragments, that can cause injury and lead to infection.
Cleanup of Flood Water

When returning to your home after a flooding emergency, be aware that flood water may contain sewage.
