Explain any 5 causes of river pollution?

  • Rubbish like crisp packets, newspaper and bags.
  • Oil
  • Poisonous substances
  • Cans, bottles and other solid objects
  • Human waste / excrement
  • -4

(1) Deposition of chemical pesticides and fertilizers into the river water.

(2) Oil, gasoline and additives leads to water pollution. Shipping is one of the non spill sources of water pollution.

(3) Mining causes water pollution in a number of ways.

(4) Chemical and industrial processes also leads to river and water pollution.

(5) Plastic and other such substances like nylon from fishing nets pollute water.

(6) Non regulated disposal of sewage is another major reason.

  • Agricultural run-off (pesticides, herbicides, fertilizer, amanure)
  • Illegal dumping
  • Indiscriminate discharge of untreated wastewater from industries, domestic settlements
  • Indiscriminate disposal of garbage, solid wastes directly into rivers
  •  Indiscriminate quarrying of sand, rock and other minerals in river beds

 Growing demands of human needs have been steadily affecting the quality of river 

water. Volume of water has been decreasing as more and more water is being used.
 Industrial wastes and sewage are dumped into water bodies, thus polluting them 
further.
 Various action plans like the Ganga Action Plan (GAP)for cleaning the polluted water 
bodies have failed to achieve the desired results.

 The main reason for the river pollution are :
(1) Discharge of untreated domestic sewage into rivers .
(2) Discharge of toxic industrial wastes into rivers .
(3) Contamination of rivers with toxic metal such as lead , arsenic , cadmium , mercury , nickel , etc .
(4) People wash clothes in rivers .
(5) Excessive use of fertilises and pesticides in agriculture than the water goes into river and pollute water .

  • Acid rain
  • Sewage ,garbage ,etc. are dumped into river
  • Human wastes
  • Deposition of chemical pesticide and fertilisers in the river
  • Plastic bag and synthetic fibres pollute the river

  1. Factories treat chemicals into the river.
  2. due to more use of pesticides,wedicides and fertilisers the river water is polluted.
  3. because of mining also the river is poluted
  4. ​many of us throw plastic and other garbage into river 
  5. disposal of sewage into river
  • -2
    five causes that pollute water are :
1) releasing of chemicals and other waste materials from different industries into rivers.
2) throwing of garbage in rivers.
3) minning causes river pollution in various ways.
4) agricultural also activities causes river pollution.
5) rivers are also get polluted by acid rain that also affect the aquatic life.

Sewage And Waste Water:?Sewage, garbage and liquid waste of households, agricultural lands?and factories are discharged into lakes and rivers. These wastes contain harmful chemicals and toxins which make the water poisonous for aquatic animals and plants.

Dumping:?Dumping of solid wastes and litters in water bodies causes huge problems. Litters include glass, plastic, aluminum, styrofoam etc. Different things take different amount of time to degrade in water. They affect aquatic plants and animals.

Industrial Waste:?Industrial waste contains pollutants like asbestos, lead, mercury and petrochemicals which are extremely harmful to both people and environment. Industrial waste is discharged into lakes and rivers by using fresh water making the water contaminated.

Oil Pollution:?Sea water gets polluted due to oil spilled from ships and tankers while traveling. The spilled oil does not dissolve in water and forms a thick sludge polluting the water.

Acid Rain:?Acid rain is pollution of water caused by air pollution. When the acidic particles caused by air pollution in the atmosphere mix with water vapor, it results in acid rain.

Global Warming:?Due to global warming, there is an increase in water temperature. This increase in temperature results in death of aquatic plants and animals. This also results in bleaching of coral reefs in water.
