The primary causes of water pollution in India are:
1. Industrial discharge of untreated effluents: Factories release harmful chemicals like heavy metals, dyes, and oils into rivers and lakes, degrading water quality and harming aquatic life.
2. Agricultural runoff containing pesticides and fertilizers: Excessive use of agrochemicals washes into water bodies, causing eutrophication and contaminating drinking water sources. These factors significantly impact water ecosystems and public health, requiring immediate attention and sustainable practices.
