Model Answer
Effect of Water Pollution on Environment:
Industries discharge organic and inorganic wastes and effluents into rivers and water bodies. These contain dyes, detergents, acids, salts, and heavy metals like lead and mercury, making water unsafe for humans and aquatic life. Thermal pollution (hot water discharge) also harms aquatic ecosystems. Pollutants seep into soil and contaminate groundwater, affecting agriculture and drinking water sources.
Three Industries Responsible:
- Paper and Pulp industries
- Textile and Dyeing industries
- Petroleum Refineries / Tanneries

Explanation
- The question has two parts — effects (2 marks) and naming industries (1 mark). Distribute your answer accordingly.
- Key terms to include: effluents, heavy metals (lead, mercury), thermal pollution, groundwater contamination.
- The textbook explicitly lists paper, pulp, chemical, textile/dyeing, petroleum refineries, and tanneries — pick any three for full marks.
- Avoid generic statements; use textbook-specific vocabulary like "organic and inorganic industrial wastes."
