What is Water Pollution?
Water pollution can be defined in several different ways. Generally it is the accumulation of one or more substances in the water to become harmful to animals, plants, people and the environment. This means that toxic chemicals or waste that has been poured into the water are not adequately filtered or destroyed and all living things that are in contact with water will be adversely affected.

What are the Reasons for Water Pollution?

In general, water pollution is caused by human activities.


Sewage: Wastewater from each house is chemically treated and poured cleanly into the sea. There are harmful bacteria or chemicals that can lead to serious health problems if they are poured into wastewaters and sewers, especially in lakes or streams. For example, waste water from houses, factories or commercial buildings can cause health problems if chemical substances or medicines are mixed.
Industrial Waste: Factories produce chemical and environmentally hazardous substances in high quantities that can affect people and the environment. Many factories do not have methods of waste disposal and disposal. These toxic waste materials can change the color and temperature of the water and also cause serious damage to the aquatic organisms.
Ship or Tanker Wastes: Oil extracted from ships or tankers constitutes 12% of the amount of oil in the ocean. The others are due to transportation reasons, sewage and discharge of garbage. De-oiling from a ship or tanker is a serious problem because in large quantities the oil is discharged only once. The people of the surrounding area and the surrounding area create serious problems for local wild marine life, fish, birds and thirst. The oils are insoluble in water and leave a thick layer of water on the surface. This prevents fish from catching air, prevents flying birds from flying in the sea, and prevents light from living in water.
Rainfalls: The burning of fossil fuels leaves an ash cloud in the atmosphere, which causes acid rain. Rains called acid rain can cause water pollution. Rain can cause dirty surfaces and waters because too much rain can transport poisonous substances on the surface of the soil to water and poison the water.
Waste disposal in Denizli: Paper, aluminum, glass, plastic or food waste is household waste. These materials can dissolve in the soil for 2 weeks or 200 years. Such goods are poured into the sea and not only damage the water pollution but also the lives of the animals in the sea.
Global Warming: Increases the temperature of the world's waters because of the greenhouse effect caused by global warming and thermal power plants. The rise of water temperature causes the death of many sea creatures. For example, an increase in water temperature has caused the coral reefs of the world to become heavily populated, and this is a great danger to the living creatures who live their lives in the seas.
What are the Types of Water Pollution?
Surface waters are the world's natural water resources. When the oceans, lakes and rivers face water pollution, this is called surface water pollution.

A large amount of water resources in the world is underground. People usually use the aquifers to get drinking water and they open wells to reach it. If these waters become polluted, it is called pollution of groundwater. Contamination of groundwater is usually caused by insecticides that squeeze into the soil, which can also affect drinking water.

Microbiological Water Pollution is a type of water pollution that causes water pollution by microorganisms such as bacteria, viruses or protozoa. Many types of microorganisms live in the water and cause both the animals living there and people to become ill.

Nutrients and Aquatic Effects Nutrients are important for plant growth and development. There are many nutrients in the wastewater and fertilizers, and they can provide plenty of grass and algae growth in the soil. This may lead to pollution of drinking water, and since algae will consume oxygen in the water, it may not leave a habitat for other living underwater.

Suspended Items, some contaminants can not dissolve in water. These materials are particulate matter and may cause water pollution. Suspended materials form a layer on the water surface, which is harmful to living creatures on the surface.

Industrial and agricultural works contain many different kinds of chemicals that pollute the water. Industrial metals and solvents pollute rivers or lakes, damage living systems and even cause infertility or death in living organisms. Insecticides can also cause water pollution, causing damage to the aquatic life, as well as animals that eat birds or fish affected by it. Petroleum is another kind of chemical that pollutes water. As a result of the disintegration of a ship, it can be poured into the oceans or seas and cause many fish to die, which can also damage sea birds flying. Such pollution is generally called Chemical Water Pollution.

What are the Dangers of Water Pollution?
The damage to health is as follows:

Swimming in contaminated waters or drinking water from them can cause problems such as disturbances, reproductive problems, typhoid or cancer. For this reason, drinking tanned water is very important.
In addition, industrial chemicals and agricultural pesticides reach the seas and then poison the fish that people eat.
The damage to the environment is as follows:

Water pollution can cause flooding due to soil loss or erosion in rivers and rivers. The pouring of oils into the water causes the animals to die, thus overcoming the natural balance.
With the increase in water temperature, coral reefs are affected by this situation and its weeping causes the ecosystem to see great damage. As hot water provides local sea animals to look for cooler regions, there is a significant change in the life in that region.
When organisms such as sewage, insecticides and fertilizers enter the water, they consume oxygen and because of the low amount of oxygen, the living conditions of underwater creatures in that area become difficult.
What are the Solutions to Prevent Water Pollution?
It is important to close when no running water is needed. This reduces the amount of contaminated water that needs to be processed by avoiding water scarcity.
We should pay attention to the things we throw from the toilet or the sink. Especially oil and garbage should not be discarded.
We should choose laundry detergents, household cleaners and toiletries as environmentally friendly.
Avoiding excessive use of fertilizers and insecticides and feeding many plants in your garden will prevent the circulation of these materials in the water.
No rubbish should be thrown into rivers, lakes and the ocean. Where you see contamination, you can help to clean it using safe materials.
