Water pollution occurs when harmful substances contaminate a stream, river, lake, ocean, aquifer, or other body of water, degrading water quality and rendering it toxic to humans or the environment, usually as a result of human activities.

Groundwater Ridding groundwater of contaminants can be difficult to impossible and costly. Once polluted, an aquifer may be unusable for decades, or even thousands of years. Surface water Nutrient pollution is the leading type of contamination in these freshwater sources. It became a major pollutant due to farm waste and fertilizer runoff. Ocean water Eighty percent of ocean pollution originates on land. Contaminants are carried from farms, factories, and cities by streams and rivers into the sea. Meanwhile, marine trash—particularly plastic—is blown in by the wind or washed in via storm drains and sewers.
