The coliform bacteria are usually found in the human intestine whose presence in the Ganga water indicates contamination by faeces and disease-causing micro-organisms. The Ganga Action Plan project was launched in 1985 to clean the Ganga and make its water free from pollution.

Answer:

Causes-

Sewage from domestic households, factories and commercial buildings

Sewage that is treated in water treatment plants is often disposed into

the sea.

Dumping solid wastes and littering by humans in rivers, lakes and oceans. Littering items include cardboard, Styrofoam, aluminum, plastic and glass.

Industrial waste from factories, which use freshwater to carry waste from the plant into rivers, contaminates waters with pollutants such as asbestos, lead, mercury and petrochemicals.

Oil Pollution caused by oil spills from tankers and oil from ship travel. Oil does not dissolve in water and forms a thick sludge.

Burning fossil fuels into the air causes the formation of acidic particles in the atmosphere. When these particles mix with water vapor, the result is acid rain.

An increase in water temperature is caused by global warming and thermal plants that use lakes and rivers to cool down mechanical equipment.

Effects-

Groundwater contamination from pesticides causes reproductive damage within wildlife in ecosystems.

Sewage, fertilizer, and agricultural run-off contain organic materials that when discharged into waters, increase the growth of algae, which causes the depletion of oxygen.

Swimming in and drinking contaminated water causes skin rashes and health problems like cancer, reproductive problems, typhoid fever and stomach sickness in humans.

Industrial chemicals and agricultural pesticides that end up in aquatic environments can accumulate in fish that are later eaten by humans.

Human-produced litter of items such as plastic bags and 6-pack rings can get aquatic animals caught and killed from suffocation.

Water pollution causes flooding due to the accumulation of solid waste and soil erosion in streams and rivers.

POLLUTION OF GANGA - DEFINITION

The river Ganga runs its course of over 2500 kilometres from Gangotri in the Himalayas to the Bay of Bengal, through Uttar Pradesh, Bihar and West Bengal.

Pollution of the river Ganga is due to activities like bathing, washing clothes, immersion of the ashes of the dead, industrial effluents and release of untreated sewage.

The coliform bacteria are usually found in the human intestine whose presence in the Ganga water indicates contamination by faeces and disease-causing micro-organisms.

The Ganga Action Plan project was launched in 1985 to clean the Ganga and make its water free from pollution.

CASE STUDY OF RIVER GANGA - DEFINITION

The settlements built along the river, as well as the dumping of waste water have resulted in the serious pollution in the Ganges. Some people even cremate and dump the bodies of the deceased into the river during holy rituals. Despite this, people still use the river to wash their clothes, bath and carry out their daily activities. WHO has stated that the Coliform bacteria in the Ganges river are over 2800 times higher than the level considered safe for humans. Worse, the leather industry dumps water polluted with chromium into the Ganges, making water there toxic and poisonous.
