Sewage discharge is the primary source of water pollution in India, accounting for over 70% of the total pollution load.

The Ganges River is considered to be the most polluted river in India due to the discharge of untreated sewage, industrial waste, and agricultural runoff.

Agricultural activities, particularly the use of fertilizers and pesticides, contribute to eutrophication, which is the process by which water bodies become enriched with nutrients, leading to excessive plant growth and oxygen depletion.

Septic tank leakage is a major cause of groundwater pollution in India, as it allows untreated sewage to seep into the ground, contaminating groundwater sources.

Drinking contaminated water can lead to various health concerns, including diarrhea, typhoid, hepatitis A, and other waterborne diseases.

To control water pollution from industrial sources, a combination of measures is necessary, including imposing strict pollution regulations, promoting the use of clean technologies, and encouraging industrial recycling.

The National River Conservation Plan (NRCP) aims to clean up polluted rivers, prevent further pollution, and promote sustainable river management through various initiatives.

Addressing water pollution in India faces several challenges, including lack of political will, inadequate infrastructure, limited public awareness, and the sheer magnitude of the problem.

Public participation plays a crucial role in controlling water pollution by raising awareness, pressuring policymakers to take action, and adopting water-saving practices.

Several water pollution control initiatives have been undertaken in India, including the Clean Ganga Mission, Yamuna Action Plan, and Namami Gange Project, with varying degrees of success.
