Sources of Water Pollution

Euthropication, global warming, atmospheric deposition, underground storage leakages, oil pollution, radioactive waste, industrial waste, marine dumping, and sewage and wastewater are sources of water pollution.

Surface water pollution is when chemicals polluted into bodies of water float and partially dissolve into the water. Surface water pollution is an increasing factor as a result of expanding industrial buildings and disposing solid materials. One source of this pollution are from factories. Factories get rid of toxic chemicals they utilise by polluting them into sewage systems. These sewage systems have a pathway that connects to bodies of water. Materials dumped into bodies of water can dissolve in the water.  Some materials take a long time to completely degrade. During this time period, animals, plants and the water is negatively affected.

Graph 1: Chemicals used in industries end up in bodies of water.







Graph 2: Solid waste disposal is a factor of surface water pollution.

Graph 3: The health of marine habitants is affected when the environment becomes enriched with nutrients. The enrichment causes algal blooms. Algae blooms is the increase in algue population. This pollution is called euthropication.





Graph 4: The greenhouse effect is a factor of global warming. Global warming can increase water temperature. A large increase in water temperature affects marine habitants.






Graph 5: Atmospheric deposition is the pollution of water caused by air pollution. Water vapour absorbs gases in the air, becoming more acidic. When it rains, the acid rain pollutes bodies of water.







Graph 6: The leakage of a tank or pipe that contains harmful substances, which contaminates water is called an underground storage leakage. This happens over time as the tank or pipe networks material (steel) corrodes.

Graph 7: Oil pollution is when oceans are polluted by oil. Oil cannot dissolve in water and forms a thick sludge in the water.



Graph 8: As nuclear waste from industrial, scientific and medical processes are dumped into the ocean, this is known as radioactive waste.




Graph 9: Industries produce pollutants which are harmful. Industrial waste is when these harmful pollutants are dumped into the water as some industries using freshwater to carry away the waste that was created.


Graph 10: Marine dumping is dumping litter into the sea. Litter takes time to degrade and can get stuck in marine animals, possibly causing death.


Graph 11: Sewage and wastewater describes water contaminated by faeces, urine and laundry waste. This water is treated by water treatment plants and the waste is disposed into the sea. Untreated sewage water affects the environment and can cause diseases such as diarrhoea.
