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] Some scholars believe that the projected peak global population of roughly 9-10 billion people could live sustainably within the earth's ecosystems if humans worked to live sustainably within planetary boundaries.
A 2006 measurement of pollution in the Ganges revealed that river water monitoring over the previous 12 years had shown fecal coliform counts of up to 100,000,000 MPN per 100 mL [29] and biological oxygen demand levels averaging over 40 mg/L in the most polluted part of the river at Varanasi. The overall rate of water-borne disease incidence ...
