Water Pollution — Prelims Strategy
Prelims Strategy
For Prelims, the strategy for water pollution should focus on factual recall and conceptual clarity. Aspirants must thoroughly understand the definitions of key terms like BOD, COD, DO, eutrophication, bioaccumulation, and emerging pollutants.
Memorize the core provisions of the Water (Prevention and Control of Pollution) Act, 1974, and the Environment (Protection) Act, 1986, including the establishment of CPCB and SPCBs. Pay close attention to the constitutional articles related to environmental protection (21, 48A, 51A(g)).
Be able to differentiate between point and non-point sources of pollution with clear examples. Map out major polluted rivers and groundwater contamination issues in India. Familiarize yourself with the objectives and key features of government schemes like Namami Gange, NRCP, and Jal Jeevan Mission.
Questions often involve identifying correct statements about these acts, schemes, or concepts, or matching pollutants with their sources/impacts. Practice MCQs that test conceptual understanding and the ability to distinguish between similar-sounding terms.
Focus on recent developments related to NGT orders or new types of pollutants as these are common current affairs hooks.
