Water pollution is a major global environmental problem because it can result in the degradation of all aquatic ecosystems – fresh, coastal, and ocean waters. [75] The specific contaminants leading to pollution in water include a wide spectrum of chemicals, pathogens, and physical changes
Topsoil runoff from farm, central Iowa (2011). Water pollution in the United States is a growing problem that became critical in the 19th century with the development of mechanized agriculture, mining, and manufacturing industries—although laws and regulations introduced in the late 20th century have improved water quality in many water bodies.

Environment destruction caused by humans is a global, ongoing problem. [4] Water pollution also cause problems to marine life. [5] Most scholars think that the project peak global world population of between 9-10 billion people, could live sustainably within the earth's ecosystems if human society worked to live sustainably within planetary ...
An IBI associates anthropogenic influences on a water body with biological activity in the water body, and is formulated using data developed from biosurveys. Biological integrity is associated with how "pristine" an environment is and its function relative to the potential or original state of an ecosystem before human alterations were imposed ...
Some of the UNECE's water related problems are of water quantity and water quality, high water stress and overexploitation of water resources, increasing droughts and floods, contaminated water resulting in water-related diseases, etc. These issues are even harder to solve due to transboundary nature of the water sources in the UNECE region.
This form of pollution can lead to many problems. One is the degradation of aquatic ecosystems. Another is spreading water-borne diseases when people use polluted water for drinking or irrigation. [33] Water pollution also reduces the ecosystem services such as drinking water provided by the water resource.
