Water pollution causes

Some Important Water Pollution Causes And Effects:

Water is very important for our life. Without water we are not able to survive in this planet. So water is very important for our survival. We know the importance of water but still we are polluting water. So im this i am going to talk about water pollution causes and effects.

Water pollution Causes:

1. Industrial waste:

Industrial waste contains polluTop tants 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.

2. Religious and Social practices:

Religious faith and social practices also add to pollution of our river waters. Carcasses of cattle and other animals are disposed in the rivers. Dead bodies are cremated on the river banks. Partially burnt bodies are also flung into the river. All this is done as a matter of religious faith and in keeping with ancient rituals. These practices pollute the river water and adversely affect the water quality.

3. Improper drainage system:

Drainage system pollution, this is the form of water pollution where sewage and normal public water supply mix up. This is seen especially in cities where water is pumped from distant out places. This occurs when there is leakage of sewage water and mixing with that of pure water supplied by municipal water pipes.

4. 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.

5. Urbanisation:

Rapid urbanisation in India during the recent decades has given rise to a number of environmental problems such as water supply, wastewater generation and its collection, treatment and disposal.Many towns and cities which came up on the banks of rivers have not given a proper thought to problem of wastewater, severage, etc.

Effects of water pollution:

1. Effects on human health:

Swimming in and drinking contaminated water causes skin rashes and health problems like cancer, reproductive problems, typhoid fever and stomach sickness in humans. Which is why it’s very important to make sure that your water is clean and safe to drink.

2. Effects on Aquatic animals:

All organic materials can be broken down or decomposed by microbial and other biological activity (biodegradation). Organic and some of the inorganic compounds exhibit a biochemical oxygen demand (BOD) because oxygen is used in the degradation process.

Oxygen is a basic requirement of almost all aquatic life. Aquatic life is adversely affected if sufficient oxygen is not available in the water. Typical sources of organic pollution are sewage from domestic and animal sources, industrial wastes from food processing, paper mills, tanneries, distilleries, sugar and other agro based industries.

3. Effects on Food chain:

Pollution disrupts the natural food chain as well. Pollutants such as lead and cadmium are eaten by tiny animals. Later, these animals are consumed by fish and shellfish, and the food chain continues to be disrupted at all higher levels.

4. Effects on Ecosystem:

Ecosystems (the interaction of living things in a place, depending on each other for life) can be severely changed or destroyed by water pollution. Many areas are now being affected by careless human pollution, and this pollution is coming back to hurt humans in many ways.

5. Effects on all living being:

The effects of water pollution are not always immediate. They are not always seen at the point of contamination. They are sometimes never known by the person responsible for the pollution. However, water pollution has a huge impact on the lives of all people. With knowledge, consideration and preparation, water pollution can be decreased. It doesn’t take much effort just a little thought.
