The causes of water pollution

Explanation:

• 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.  
• GLOBAL WARMING : An increase in water temperature can result in the death of many aquatic organisms and disrupt many marine habitats.
• ATMOSPHERIC WATER POLLUTION : Atmospheric deposition is the pollution of water caused by air pollution. In the atmosphere, water particles mix with carbon dioxide sulfur dioxide and nitrogen oxides, this forms a weak acid.
• UNDERGROUND STORAGE LEAKAGES : A tank or piping network that has at least 10 percent of its volume underground is known as an underground storage tank (UST). They often store substances such as petroleum, that are harmful to the surrounding environment should it become contaminated.
• OIL POLLUTION IN WATER : Oceans are polluted by oil on a daily basis from oil spills, routine shipping, run-offs and dumping.   Oil spills make up about 12% of the oil that enters the ocean. The rest come from shipping travel, drains and dumping.
• NUCLEAR WASTE : Nuclear waste is produced from industrial, medical and scientific processes that use radioactive material. Nuclear waste can have detrimental effects on marine habitats.
• INDUSTRIAL WATER : Industry is a huge source of water pollution, it produces pollutants that are extremely harmful to people and the environment.
• 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.
• SEWAGE AND WASTEWATER POLLUTION : Domestic households, industrial and agricultural practices produce wastewater that can cause pollution of many lakes and rivers. Sewage is the term used for wastewater that often contains faeces, urine and laundry waste.
