Floods and other disasters can damage drinking water wells and lead to groundwater and well contamination. Floodwater can contaminate well water with livestock waste, human sewage, chemicals, and other contaminants that can lead to illness when used for drinking, bathing, and other hygiene activities. Dug wells, bored wells, and other wells less than 50 feet deep are more likely to be contaminated, even if damage is not apparent (source CDC).
