Question

What are the causes of water pollution? Discuss how you can contribute to reducing water pollution.

Answer 1

Water pollution is produced by the addition of:

1. unfavourable compounds such as fertilisers and pesticides, as well as any harmful substances, to bodies of water.

2. sewage, entering directly into the water body. 

3. hot water from the power plant, which raises the temperature and decreases the dissolved oxygen in the water & kills aquatic life.

4. industrial effluents or radioactive chemicals found in bodies of water.

To combat water contamination, we can implement the following strategies:

1. Sewer pipes should not be connected directly to water bodies.

2. We should not dispose of garbage or household waste in water bodies.

3. We should not dump harmful substances into water bodies.

4. Avoid washing garments near water bodies because it adds a lot of detergent to them.

5. Trees should be planted near river banks to prevent soil erosion, which contributes to the siltation of water bodies.
