Sources of Water Pollution — Prelims Strategy
Prelims Strategy
For Prelims, the strategy for 'Sources of Water Pollution' should focus on precise factual recall and clear conceptual understanding. First, master the distinction between point and non-point sources, along with multiple examples for each.
Be able to identify specific pollutants (e.g., heavy metals, dyes, APIs, nitrates, phosphates, pathogens) and their primary industrial, domestic, or agricultural origins. Memorize the key provisions and establishment dates of the Water (Prevention and Control of Pollution) Act, 1974, and the Environment (Protection) Act, 1986, as well as relevant constitutional articles (21, 48A, 51A(g)).
Pay attention to recent developments and reports from CPCB or NGT, as these often form the basis of current affairs-linked questions. Practice MCQs that test classification, pollutant-source matching, and legal frameworks.
Vyyuha recommends creating flashcards for pollutant-source pairs and a timeline for environmental legislation. Focus on understanding the 'why' behind each source's impact, e.g., why phosphates cause eutrophication, rather than just rote memorization.
This will help in tackling application-based questions.
