Water pollution is a large set of adverse effects upon water bodies (lakes, rivers, oceans, groundwater) caused by human activities. Water pollution is caused by;
- Increases in nutrient loading may lead to eutrophication.
-
Organic wastes such as sewage and farm waste impose high oxygen demands on the receiving water leading to oxygen depletion with potentially severe impacts on the whole eco-system.
- Industries discharge a variety of pollutants in their wastewater including heavy metals, organic toxins, oils, nutrients, and solids.
- Discharges can also have thermal effects, especially those from power stations, and these too reduce the available oxygen.
