Waste from home, and industry pollutes lakes, rivers, and seawater through waterways. This causes a lot of damage to the environment.

Sources of water pollution:

Water pollution occurs by the following sources.

Domestic waste: Domestics waste is also called “Household waste”. Waste from homes such as plastic, paper, wood, and combustible materials are poured into the water can cause water pollution.

Industrial effluents: Industrial waste containing toxic chemicals, acids, alkalis, metallic salts, phenols, cyanide, ammonia, radioactive substances, etc. These are the sources of water pollution. They also cause thermal pollution of water.

Synthetic Detergents: Synthetic detergents used in washing and cleaning contaminate water with foam and other waste.

Agrochemicals: Chemicals such as agricultural fertilizers and pesticides contaminate ponds and rivers by mixing with rainwater.

Oil leakage: Oil spillage into sea-water during drilling and shipment pollute water.

Waste heat: Waste heat from industrial discharges increases the temperature of water bodies and affects the distribution and survival of sensitive species.

Control of water pollution:

Water pollution can be controlled to some extent by following some simple steps given below:

  • Stop pouring domestic waste into the water like lakes, rivers, etc…
  • Avoiding the use of Agrochemicals and fertilizers.
  • Rainwater must be preserved by using the method of rainwater harvesting.
  • Industrial waste should be prevented from mixing with water.
  • One interesting thing is that water pollution can also be controlled by planting trees.


Water pollution affects every being on earth. Our country India also facing the problem of water pollution. The Government has already launched many schemes to control water pollution and to preserve water for future generations. As a citizen, it is our responsibility to prevent water pollution.

Pollution of water:

Nowadays water pollution has become a dangerous problem all over the world. Water is an essential element for survival on planet earth. Now, we will discuss some of the main effects of water pollution on human beings and the environment.

Effects of water pollution:

Scarcity of safe water: Water pollution largely affects drinking water needs. As a result, it is estimated that one billion people worldwide haven’t access to safe drinking water.

Diseases: Waterborne diseases, also known as dirty water diseases result from consuming contaminated water. Around 2.3 billion people globally suffer from many diseases like diarrheal diseases, typhoid, infectious hepatitis, and paratyphoid are also caused.

Affects food production: Water pollution affects food production also. Agriculture itself pollutes water due to the usage of fertilizers, pesticides, and herbicides.

Affects aquatic life: Chemicals and bacteria in water sources such as ponds or lakes can cause the presence of algae. This reduces the oxygen level in the water. It is harmful to aquatic life.

Control of pollution of water:

Now we will discuss about how to reduce water pollution from point sources and non-point sources.

Non-point sources:

  1. Use of agrochemicals like pesticides and fertilizers which will reduce their surface run-off and leaching.
  2. Adopting integrated pest management to reduce reliance on pesticides.
  3. Prevent run-off of manure. Divert such a run-off to the basin for settlement. The nutrient-rich water can be used as fertilizer in the fields.
  4. Separate drainage of sewage and rainwater should be provided to prevent the overflow of sewage with rainwater.
  5. Planting trees would reduce pollution by sediments and will also prevent soil erosion.

point sources:

  1. Treatment of wastewater is essential before being discharged.
  2. Wastewater should be properly treated by primary and secondary treatments to reduce BOD, COD, levels upto the permissible levels for discharge.
  3. Advanced treatment for removal of nitrates and phosphates will prevent eutrophication.
  4. Before the discharge of wastewater, it should be disinfected to kill the disease-causing organisms like bacteria.

pollution of water


Water pollution means the contamination of water by some pollutants. World has being faced a dangerous environmental pollution. Water pollution is a major problem faced in India. According to the Global environmental statistics the rain water is morely getting polluted. Another major source of water pollution is industrial effluents and sewage.

Types of water pollution:

Water pollution is classified into two types:

  • Groundwater pollution
  • Surface water pollution

Groundwater Pollution:- Groundwater forms about 6.2% of the total water available on earth and is about 30 times more than surface water. Septic tanks, industry, deep good injection, mining, etc. are mainly responsible for groundwater pollution.

Surface Water Pollution:- Some examples of surface water pollution are pollution of lakes, rivers, seas, oceans, and most of the water bodies that are open. Surface water pollution is mostly caused by sewage, industrial effluents, detergents, chemicals, and so on.

Causes of water pollution:

Pollution water is caused by the following sources. Water pollution is mainly caused by various human activities.

Sewage: The sewage waste from households, agricultural activities, and from other places. These sewage wastes are dumping into the water like nearby lakes, rivers, etc. Some pollutants like chemicals and toxicants mixed up with water and pollute it.

Industrial waste: Dumping the industrial waste directly into the water without any proper treatment can cause pollution of water. Many industries are not following the rules and regulations of Government. That why many rivers like Ganga, Yamuna, etc, are polluted.

Agricultural activities: Using chemicals like fertilizers, pesticides, etc for agricultural purposes can cause pollution of water. the chemicals are absorbed into the soil and mixed with groundwater can create water pollution and also can cause soil pollution.

Oil: During the process of shipment and drilling oil spillage into the water can cause water pollution.

Eutrophication: Eutrophication means enriched nutrients and minerals are present in the water bodies can cause to create algae in the water. It reduces the water quality and affects the aquatic animals and plants by reducing the oxygen level.

Waste heat from industries: Pouring of waste heat from industries directly into the water can affect aquatic life.

Preventive measures of water pollution

Water pollution can be reduced by following the below measures.

Water conservation: Although water is useful to human beings in many ways, drinking water is a major and basic need. Conserving drinking water should strive to be the main goal of man. Waste of water has become a serious problem these days. Care should be taken not to waste water in every home and industry.

Sewage treatment: Sewage treatment is another important step to reduce water pollution. Industries must eliminate toxic substances and hazardous chemicals before releasing waste into water.

Proper usage of chemicals in agricultural fields: Proper use of chemicals in farms: To reduce water pollution, farmers should reduce the use of chemicals in the fields or use chemicals as per government instructions. Care should be taken not to mix the chemicals in the water.

Educating people about water pollution: People need to be made aware of how dangerous water pollution is. Teach them how to dispose of household waste without mixing it with water sources.

Media Involvement: Advertisements about the importance of water on TVs and radios raise awareness among the public about water pollution. Through these people learn how to conserve water.


We can’t live without water. Water is necessary for life in every moment. Everyone has a great responsibility to reduce pollution of water.

Human activities are the main sources of pollution of water like Sewage, industrial effluents, oil leakage, agrochemicals, etc. We must fight against water pollution.
