Industry, agriculture and energy production all generate wastes that can pollute air,
water and soil. Another example is the release of so-called greenhouse gases such as
carbon dioxide, methane and nitrous oxide, which contribute to human-induced climate
change.
-Urbanization and Deforestation
Even though it does not have a direct impact on water quality, urbanization and deforestation have a lot of indirect effects. For instance, cutting down trees and concreting over large areas generates an acceleration of flows which does not give enough time for water to infiltrate and be purified by the ground.

-Agriculture
Agriculture has an impact on water pollution due to the use of chemicals such as fertilizers, pesticides, fungicides, herbicides or insecticides running off in the water, as well as livestock excrement, manure and methane (greenhouse effect). Regarding aquaculture, pollution is directly in the water, 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 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 like acid rain which then flows to streams, lakes, and other stretches of water.

Radioactive waste
Generated - among others - by 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 as marine resources.
