Which hazard can lead to contamination of water sources in Assam?

Fire
Landslide
Flood
Earthquake

The correct answer is: c) Flood.

Flood is a hazard that can lead to contamination of water sources in Assam. Floods can cause the following problems:

  • Pollution of water sources: Floodwaters can pick up and carry pollutants from the land, including sewage, industrial waste, and agricultural chemicals. These pollutants can contaminate drinking water supplies and make people sick.
  • Damage to water infrastructure: Floods can damage water treatment plants and other infrastructure that is used to provide clean water. This can make it difficult to provide clean water to people who need it.
  • Disruption of water supplies: Floods can also disrupt water supplies by making it difficult to access water sources or by contaminating water sources. This can make it difficult for people to get the water they need for drinking, bathing, and cooking.

Landslides, fires, and earthquakes can also cause contamination of water sources, but they are less likely to do so than floods. Landslides can contaminate water sources by carrying soil and rocks into rivers and streams. Fires can contaminate water sources by burning trees and other vegetation, which can release pollutants into the air. Earthquakes can damage water infrastructure, which can make it difficult to provide clean water.

In conclusion, flood is the hazard that is most likely to lead to contamination of water sources in Assam.
