Some forms of pollution include thermal pollution coming from the power plants or factories which causes issues in the rivers. With the rising temperature in the water, it can reduce the amount of oxygen present in the water and decrease the level of aquatic life that the river can support.

Water pollution is caused due to several reasons. Here are the few major causes of water pollution:
Sewage And Waste Water: Sewage, garbage and liquid waste of households, agricultural lands and factories are discharged into lakes and rivers. These wastes contain harmful chemicals and toxins which make the water poisonous for aquatic animals and plants.
Dumping: Dumping of solid wastes and litters in water bodies causes huge problems. Litters include glass, plastic, aluminum, styrofoam etc. Different things take different amount of time to degrade in water. They affect aquatic plants and animals.
Industrial Waste: Industrial waste contains pollutants like asbestos, lead, mercury and petrochemicals which are extremely harmful to both people and environment. Industrial waste is discharged into lakes and rivers by using fresh water making the water contaminated.
Oil Pollution: Sea water gets polluted due to oil spilled from ships and tankers while traveling. The spilled oil does not dissolve in water and forms a thick sludge polluting the water.
Acid Rain: Acid rain is pollution of water caused by air pollution. When the acidic particles caused by air pollution in the atmosphere mix with water vapor, it results in acid rain.
Global Warming: Due to global warming, there is an increase in water temperature. This increase in temperature results in death of aquatic plants and animals. This also results in bleaching of coral reefs in water.
Eutrophication: Eutrophication is an increased level of nutrients in water bodies. This results in bloom of algae in water. It also depletes the oxygen in water, which negatively affects fish and other aquatic animal population.
Ways to Prevent Water Pollution
1. Do not dump in or around rivers.
Dumping is one of the leading causes of water pollution, and you can keep freshwater sources from becoming contaminated by refraining from dumping in them. No matter what you might be dumping, whether it’s solid or liquid waste or even something you feel might not be all that harmful, you’ll be introducing a new substance into the water supply. This automatically contaminates it and starts it on a fast path toward full pollution. Keep trash and waste out of rivers in order to keep drinking water sources safe.
2. Clean up rivers that have a lot of trash in and around them.
If you notice a lot of dumping going on in and around rivers in your area, it’s not too late to prevent full-on pollution of these water sources. Get involved and start cleaning them up right away to have the best possible chance of preventing long-term effects from setting in. If you see litter on the banks of rivers, stop and pick it up. A few pieces of litter may soon escalate into a lot of dumping that can’t be reversed so easily, but you can do a lot to prevent pollution by picking up trash when you see it, whether it’s big or small.
3. Clean and maintain septic systems appropriately.
This may not be entirely up to you, depending on your city or county, but if you have a septic system try to do your part to keep it as clean and well-maintained as possible. Septic systems have a tendency to get too dirty or to start leaking, and when this happens, human waste is exposed to groundwater almost immediately. If you live near freshwater sources, this can also further pollute the surface water easily. You can prevent human waste pollution in water by making sure your septic system is fully functional and in good shape at all times. Call for maintenance checks at least twice a year.
