Unveiling The Hidden Dangers: Understanding River Water Pollution

River water pollution is the contamination of water bodies, including rivers, with a negative impact on their uses. It is usually a result of human activities such as sewage discharges, industrial activities, agricultural activities, and urban runoff. Water pollution may affect either surface water or groundwater. This form of pollution can lead to many problems, including the degradation of aquatic ecosystems and spreading water-borne diseases.

Dead fish floating on the river is a sign of water pollution

If you see dead fish floating on the river or notice that the water is discoloured and smelly, it could be a sign of pollutants such as cyanide, zinc, lead, copper, cadmin and mercury. These substances may enter the water in such high concentrations that fish and other animals are killed immediately. Sometimes the pollutants enter a food chain and accumulate until they reach toxic levels, eventually killing birds, fish and mammals.

If large amounts of fertiliser or farm waste drain into a river, the concentration of nitrate and phosphate in the water increases considerably. Algae use these substances to grow and multiply rapidly turning the water green. If oil enters a slow-moving river, it forms a rainbow-coloured film over the entire surface preventing oxygen from entering the water. On larger stretches of water, the oil contaminates the feathers of water birds and when they preen the oil enters the gut and kills them.

Water pollution may affect either surface water or groundwater. This form of pollution can lead to many problems. One is the degradation of aquatic ecosystems. Another is spreading water-borne diseases when people use polluted water for drinking or irrigation. The World Health Organisation (WHO) says that polluted water is water whose composition has been changed to the extent that it is unusable. In other words, it is toxic water that cannot be drunk or used for essential purposes like agriculture, and which also causes diseases like diarrhoea, cholera, dysentery, typhoid and poliomyelitis that kill more than 500,000 people worldwide every year.

Oil entering a river forms a rainbow-coloured film over the surface

When oil enters a slow-moving river, it forms a rainbow-coloured film over the entire surface. This film prevents oxygen from entering the water, which can lead to degradation of the aquatic ecosystem and spread of water-borne diseases.

The rainbow-coloured film is caused by the oil contaminating the water, which can happen when large amounts of fertiliser or farm waste drain into a river. This can lead to an increase in the concentration of nitrate and phosphate in the water, which can cause algae to grow and multiply rapidly, turning the water green.

When oil enters a river, it can also contaminate the feathers of water birds, which can be lethal. When these birds preen themselves, the oil can enter their gut and kill them.

The rainbow-coloured film can also be caused by other pollutants, such as cyanide, zinc, lead, copper, cadmin, and mercury. These substances can enter the water in high concentrations, which can kill fish and other animals immediately.

It is important to report any incidents of river pollution to the Pollution Control officer at the Water Authority. This can help to prevent further damage to the aquatic ecosystem and reduce the spread of water-borne diseases.

Fertilisers and farm waste can increase nitrate and phosphate in the water

Water pollution is the contamination of water bodies with a negative impact on their uses. It is usually a result of human activities. Water bodies include lakes, rivers, oceans, aquifers, reservoirs and groundwater. Water pollution results when contaminants mix with these water bodies. Contaminants can come from one of four main sources. These are sewage discharges, industrial activities, agricultural activities, and urban runoff including stormwater. Water pollution may affect either surface water or groundwater. This form of pollution can lead to many problems. One is the degradation of aquatic ecosystems. Another is spreading water-borne diseases when people use polluted water for drinking or irrigation.

If large amounts of fertiliser or farm waste drain into a river, the concentration of nitrate and phosphate in the water increases considerably. Algae use these substances to grow and multiply rapidly turning the water green.

Cyanide, zinc, lead, copper, cadmin and mercury are also examples of pollutants that may enter the water in such high concentrations that fish and other animals are killed immediately. These substances may enter the water in such high concentrations that fish and other animals are killed immediately. Sometimes the pollutants enter a food chain and accumulate until they reach toxic levels, eventually killing birds, fish and mammals.

The main water pollutants include bacteria, viruses, parasites, fertilisers, pesticides, pharmaceutical products, nitrates, phosphates, plastics, faecal waste and even radioactive substances.

If you see dead fish floating on the river or notice that the water is discoloured and smelly, any one of the following forms of pollution may be the cause. All incidents of river pollution should be reported to the Pollution Control officer at the Water Authority giving as much detail as you can: date, time, exact place and precisely what you saw.

These levels mean that the sacred river has become synonymous with water pollution, a worldwide problem affecting one in every three people on the planet, according to the United Nations (UN).
