Water pollution causes
What are the sources of water pollution? Unsurprisingly, deed is primarily responsible for water pollution, even if natural phenomenon - such as landslides and floods - can likewise contribute to degrade the water quality.

Sewage and wastewater
Inadequate sewage collection and treatment are sources of water pollution. According to the United Nations, more than 80% of the worldwide wastewater goes back in the environment without beingness treated or reused.

Urbanization and deforestation
Fifty-fifty though information technology does not have a straight affect on water quality, urbanization and deforestation have a lot of indirect effects. For instance, cutting down trees and concreting over big areas generates an acceleration of flows which does not give enough fourth dimension for water to infiltrate and be purified by the footing.

Agriculture
Agriculture has an impact on water pollution due to the use of chemicals such equally fertilizers, pesticides, fungicides, herbicides or insecticides running off in the water, too equally livestock excrement, manure and marsh gas (greenhouse issue). Regarding aquaculture, pollution is directly in the h2o, as excess food and fertilizers are causing dystrophication.

Industries
Industries produce a lot of waste containing toxic chemicals and pollutants. A huge amount of the industrial waste matter is drained in the fresh water which then flows into canals, rivers and eventually in the sea. Another source of water pollution is the burning of fossil fuels, causing air pollution similar acrid rain which then flows to streams, lakes, and other stretches of h2o.
Marine dumping
Everyday, garbage such as plastic, paper, aluminum, nutrient, drinking glass, or rubber are deposited into the body of water. These items have weeks to hundreds of years to decompose, and thus they are a major crusade for water pollution.

Radioactive waste
Generated - among others - past power plants and uranium mining, radioactive waste can linger in the environment for thousands of years. When these substances are released accidentally or disposed improperly, they threaten groundwater, surface water, as well equally marine resources.
