Question

Read the paragraph and answer the questions following it.

Water is essential for life. Without water, there would be no life. We usually take water as granted for its purity, but we must ensure the quality of water. Pollution of water originates from human activities. Through different paths, pollution reaches to groundwater. Easily identified source or place of pollution is called a point source, e.g.– municipal and industrial discharge pipes, where pollutants enter the water source. Non–point sources of pollution are those where a source of pollution can not be easily identified, e.g.– agricultural runoff, acid rain, etc.

1) How do you classify the various sources of water pollution?

2) What are the point sources of water pollution?

3) Name any two non-point sources of water pollution?

Answer 1

1. Point sources and non-point sources are two categories used to categorize different types of water contamination.
2. Point sources of water pollution, such as industries, power plants, etc., are the sources or locations of contamination that are immediately recognizable.
3. Acid rain and agricultural runoff are both non-point causes of water contamination.
