During and after flooding, clean water supplies are often contaminated with various types of hazardous substances from human and livestock waste, industrial chemicals, physical objects and more.

The lack of power can also affect drinking water treatment and water supply.

This makes it difficult for people to access drinking water or leaving them with contaminated water.
