- River dumping.
- Marine Dumping.
What pollution is in the ocean?
Marine pollution is a growing problem in today’s world. Our ocean is being flooded with two main types of pollution: chemicals and trash. Chemical contamination, or nutrient pollution, is concerning for health, environmental, and economic reasons.
How does water pollution affect the environment?
The main problem caused by water pollution is the effect it has on aquatic life. Dead fish, birds, dolphins, and many other animals often wind up on beaches, killed by pollutants in their habitat. Pollution disrupts the natural food chain as well. Pollutants such as lead and cadmium are eaten by tiny animals.

How did water pollution start?
For centuries, humans unknowingly contaminated sources of drinking water with raw sewage, which led to diseases such as cholera and typhoid. Water pollution intensified with the advent of the Industrial Revolution, when factories began releasing pollutants directly into rivers and streams.
What factors cause water pollution?

What are facts about water pollution?
Water Pollution Facts One of the prominent causes of water pollution is extensive eutrophication caused by agricultural, sewage, animal, human and industrial runoff, resulting in excessive concentrations of nutrients, such as phosphorus and nitrogen. This results in enhanced plant and depleted animal life due to lack of oxygen, creating a dead zone.
How do you pollute water?

How does pollution impact water?
Water pollutants alter the overall chemistry of the water, causing changes in acidity, conductivity and temperature. These in turn have an effect on the marine life. Acid rain contains sulfate particles, which can harm fishes, sea organisms, and plant life in lakes and rivers.
