How flooding affects water quality: Flood events can introduce sewage, agricultural runoff, and industrial chemicals into water supplies.

Residents in flood-prone areas should consider flood insurance even outside FEMA zones — over 25% of flood claims come from low-to-moderate risk areas. After any flood event, test your water before drinking.
