It is a primary cause of eutrophication of surface waters (lakes, rivers and coastal waters ), in which excess nutrients, usually nitrogen or phosphorus ...
Water research during the late 1970s and 1980s indicated that stormwater runoff was a significant cause of water quality impairment in many parts of the US. [25] Research on stormwater pollution continues in the 21st century, with findings that urban runoff is a ongoing source of water quality problems nationwide.
Texas has the dubious distinction of leading the nation in polluted waterways. A new report draws upon self disclosed data by industrial facilities provided to the EPA. The study counted 17 ...

It is a high-profile problem due to the use of deep tube wells for water supply in the Ganges Delta, causing serious arsenic poisoning to large numbers of people. A ...
In 2021, a research by the American Association for the Advancement of Science on the world's rivers ranked the Pasig River as the largest contributor of plastic waste to the world's oceans, additionally claiming that 28% of the rivers causing plastic pollution globally are in the Philippines.
