Which of the following are non-point sources of pollution in rivers? ...
Non-point sources of pollution in rivers refer to the diffuse sources of pollution that cannot be traced back to a specific location. These sources contribute to the overall degradation of water quality in rivers. The given options are:
1. Surface drains carrying municipal sewage: Municipal sewage is a major non-point source of pollution in rivers. Surface drains that carry sewage from cities and towns often discharge untreated or partially treated wastewater into rivers, leading to contamination and deterioration of water quality.
2. Run-off from agricultural fields: Agricultural activities contribute significantly to non-point source pollution in rivers. Run-off from fields carries fertilizers, pesticides, and sediment into rivers, resulting in nutrient enrichment, water contamination, and eutrophication.
3. Dumping of un-burnt/half-burnt dead bodies: Dumping of un-burnt or half-burnt dead bodies into rivers is a form of pollution that can have severe ecological and health impacts. It can introduce pathogens into the water, leading to the spread of diseases and contamination of the river ecosystem.
4. Dhobi ghats: Dhobi ghats, which are outdoor laundry areas where clothes are washed, can also contribute to non-point source pollution in rivers. The detergents and chemicals used in washing clothes can enter the river through run-off, leading to water pollution.
5. Effluents from industries: Industrial effluents are a significant source of non-point pollution in rivers. Discharge of untreated or inadequately treated industrial waste into rivers can introduce toxic substances, heavy metals, and other pollutants, causing harm to aquatic life and deteriorating water quality.
Based on the given options, the correct answer is option (c) 2, 3, and 4 only. Surface drains carrying municipal sewage and effluents from industries are point sources of pollution, while run-off from agricultural fields, dumping of un-burnt/half-burnt dead bodies, and dhobi ghats are non-point sources of pollution in rivers.

Which of the following are non-point sources of pollution in rivers? ...
- Point sources: These are organized sources of pollution where the pollution load can be measured, e.g. surface drains carrying municipal sewage or industrial effluents, sewage pumping stations and sewerage systems, trade effluents from industries, etc. Pollution loads due to untreated sewage is one of the main reasons threatening the ecological health of rivers. Most of the urban lakes in the country are also facing similar challenges.
- Non-point sources: These are non-measurable sources of pollution such as run-off from agricultural fields carrying chemicals and fertilizers, run-off from solid waste dumps and areas used for open defecation, dumping of un-burnt/half-burnt dead bodies and animal carcasses, dhobi ghats, cattle wallowing, etc.
- Out of the total measurable pollution in the rivers from various point sources, around 75% is contribut ed by municipal sewage from towns located along the banks of rivers and remaining 25% by industrial effluents.
