Causes, Dangers and Prevention of Water Pollution

Water Pollution


Causes of Water Pollution


Sewage and water waste – Domestic households, industrial and agricultural practices produce wastewater that can cause pollution of many lakes and rivers

Marine Dumping – Dumping of litter in the sea can cause huge problems. Litter items such as 6-pack ring packaging can get caught in marine animals and may result in death.

Industrial waste – Industry is a huge source of water pollution, it produces pollutants that are extremely harmful to people and the environment.

Radioactive waste – Nuclear waste is produced from industrial, medical and scientific processes that use radioactive material. Nuclear waste can have detrimental effects on marine habitats

Oil pollution – Oceans are polluted by oil on a daily basis from oil spills, routine shipping, run-offs and dumping.

Atmospheric deposition – Atmospheric deposition is the pollution of water caused by air pollution.

Global warming – An increase in water temperature can result in the death of many aquatic organisms and disrupt many marine habitats.

Eutrophication – Eutrophication is when the environment becomes enriched with nutrients. This can be a problem in marine habitats such as lakes as it can cause algal blooms.



Dangers of Water Pollution

All types of water pollution are harmful to humans and animals. Water pollution might not damage our health right away but can be harmful after a long of exposure.Heavy metals from industrial purposes can gather in nearby lakes and rivers. These are toxic to marine life such as fish and to humans who eat them.

Industrial waste contains toxic compounds that damage the health of water animals. Some of the compounds in industrial waste may only have a mild effect but some can be fatal.

Organic nutrients cause an increase in algae and deplete oxygen from the water column. This causes the suffocation of fish.

Sulphate particles from acid rain can harm the health of marine life in the rivers and lakes.


Prevention of Water Pollution

Save water by turning off the tap when water is not needed. This helps prevent water shortages and reduces the amount of contaminated water that needs treatment.

Be careful about what you throw down your sink or toilet.

Use environmentally household products, such as washing powder, household cleaning agents and toiletries.

By having more plants in your garden you are preventing contaminated water from running off into nearby water sources.

Don’t throw litter into rivers, lakes or oceans.
