Thermal pollutants are harmful to health and this polluted water cannot be used in any other terms. The liquid fraction of mineral oil and crude oil also causes pollution of water that is mixed from the wastages of industries. Usage of heavy metals also causes severe pollution to the water. 

Components causing water pollution

  • Thermal pollutants are mixed in water, and it results in reducing the purity of water. Carbonic compounds are often found to be mixed with water and pollute pure water. 
  • Oil and derivatives are important components that lead to polluting water. 
  • Vegetable and animal fat, which includes triglycerides are often found to be mixed in water and resulting in polluting water.    

Important reasons for water pollution

Reasons 

Explanation 

Discharge of radioactive wastes

In recent times, wastages of radioactive materials are found to be dumped in water bodies to save these from being mixed with other natural components. As a result, the water is getting polluted, as radioactive materials are not healthy components. Groundwater is found to be more prevalent and the overall environment is negatively affected by these components.   

Rapid urbanization 

Development in urbanization is found to be increasing rapidly in current times. The degradation of the water supply system is linked to the urbanization process. Some important pollutants that are found within runoff of urban areas are nutrients, sediments, heavy metals, and pathogenic bacteria. Oxygen-demanding substances, petroleum hydrocarbons are harmful components that are extracted from urban areas and are causing water pollution. 

Disposal of sewage in an improper way

Domestic sewage can cause severe damage to water by being contaminated. Partially treated sewage is found to cause harm to environmental objects. An important reason for the flood is also the disposal of domestic sewage in an improper manner.   

Spills of oil in water

Products that contain oil are harmful to water bodies that cannot be dissolved in any form. Oil forms thick sludge in water and becomes a reason for pollution. Water becomes inconsumable after mixing with the oil. Water vehicles such as submarines and ships use oils for transportation. Some of the cargo ships are loaded with oil and during the journey; some portion of the oil is left in the water bodies causing pollution. This is one of the most important causes of water pollution.  

Dumping chemical waste from industries

Most industries are found to be developed at the bank of a river. The liquid and solid waste materials, from the factories, are dumped into the river bodies, which increases the portion of water pollution.  

Fertilizer 

Usage of fertilizer is increasing in harvesting procedures. Fertilizer is used in farming to increase the growth of plants. These fertilizers are drained with rainwater and mixed with nearby water bodies.    

Impacts of water pollution

  • The balance of biodiversity is destroyed by water pollution.
  • An important effect of water pollution is the disturbance in the food system by water pollution. 
  • Shortage of consumable water can be found in the future.
  • Various diseases such as diarrhea and kidney disease are results of water pollution.
  • The mortality rate is also negatively affected by water pollution. 

Solution for reducing water pollution 

  • Using environment friendly components in harvesting can reduce water pollution.
  • Reducing the usage of fertilizer is an important solution.
  • The usage of plastic can be reduced.
  • Consumption of more organic food can be mentioned.
  • Chemical usage can be reduced.
  • Successful implementation of the water conservation process is an important solution for industry.
  • Using rainwater to do basic household work and trying to recycle the wastewater is a solution.

Conclusion

Thermal water pollution is the changes in the temperature of the water that causes difficulties for aquatic lives. Physical properties of water are found to be changed as a result of thermal water pollution. Various aquatic animals are found to face suffocation as a result of split oil. An excessive amount of radioactive pollutants within a water body is an important reason for water pollution. Excessive fertilizer results in affecting the purity of water, which is an important part of causes of water pollution.
