River Pollution — Prelims Strategy

Prelims Strategy

For Prelims preparation, focus on memorizing specific facts, dates, and institutional details. Key areas include: chronological development of policies (GAP 1985, NRCP 1995, NMCG 2014), institutional framework (CPCB, SPCBs, NMCG structure), legal provisions (Water Act 1974, EPA 1986, key amendments), water quality parameters (BOD, COD, DO standards for different categories), budget allocations and achievements of major programs, and recent developments including Supreme Court directions and technological innovations.

Practice elimination techniques by understanding common traps - confusing dates of different programs, mixing up institutional roles and functions, and incorrect linkage between causes and effects of pollution.

Pay special attention to current affairs connections, particularly NMCG developments, new STP inaugurations, and pollution incidents. Use mnemonics like RIVERS (Runoff, Industrial, Volume, Eutrophication, Regulatory, Solutions) for systematic recall.

Regular revision of factual data is crucial as questions often test specific details rather than conceptual understanding.

Also build Paper II skills

Climate data, pollution metrics, and treaty timelines are natural practice for CSAT data interpretation and careful reading. CSAT hub.
