Cause of Eutrophication!
•Nitrates from fertilisers applied to surrounding land.
•Phosphates from animal slurry.
•Phosphates from sewage from settlements and holiday centres.
•Wastewater municipal and industrial).
•Runoff from waste disposal systems.
•Runoff and infiltration from animal feedlots.
•Runoff from mines, oil fields, and wered industrial sites.
•Overflows of combined storm and sanitary sewers.
•Runoff from construction sites less than 220,000 ft.
•And of course, untreated sewage.

Effects of Eutrophication
Eutrophication is a natural environmental issue. It will happen no matter what people do. It's been happening since the beginning of time. Natural eutrophication is supposed to develop over centuries of time. Human activity caused the process to speed up majorly. Instead of developing over centuries, eutrophication is now developing over decades. For example, if natural eutrophication were to develop over 200 years, then cultural eutrophication (increased by human activity) would develop over 20 years. But whether it's fertilizers or pesticides with phosporus or nitrogen from farmlands, pollution from factories, sewage works, pollution from humans, or pollution from cleaners, lubricants, and many more, nitrates and/or phosphates are going to enter a body of freshwater. It could be a pond, a lake, a river, or any other body of water. Eventually all bodies of water will be covered with eutrophication if things continue going the way they are.
