The United Nations Environment Programme (UNEP) reports that once water is contaminated, it is difficult, costly, and often impossible to remove the pollutants. Currently,80% of global wastewater goes untreated, and is contaminated by a wide range of substances, from human waste to highly toxic industrial discharges. The type and amount of pollutants in freshwater determines its suitability for human uses such as drinking, bathing, and agriculture.

Pollution of freshwater ecosystems can also impact the habitat and quality of life of fish and other wildlife. This can include pathogens (largely from human and animal waste), organic matter (including nutrients from agricultural run-off such as nitrogen or phosphorus), chemical pollution (from irrigation, domestic wastewater and runoff of mines into rivers) and salinity. Plastics, and chemicals of emerging concern, such as certain pharmaceutical products, are issues for which their extent and impacts on freshwater are largely unknown. A preliminary assessment of water quality in rivers in Latin America, Africa and Asia, “A Snapshot of the World’s Water Quality” (Ringler, et al.,2016), estimated that severe pathogenic pollution affects around one third of all rivers, severe organic pollution around one seventh of all rivers, and severe and moderate salinity pollution around one-tenth of all rivers in these regions.
