"Water pollution (or aquatic pollution) is the contamination of water bodies, usually as a result of human activities, so that it negatively affects its uses."
Contamination of water bodies through spillage and runoff from transportation vehicles carrying hazardous materials or from oil leaks.
"Contaminants can come from one of four main sources: sewage discharges, industrial activities, agricultural activities, and urban runoff including stormwater."
"This form of pollution can lead to many problems, such as the degradation of aquatic ecosystems."
"Spreading water-borne diseases when people use polluted water for drinking or irrigation."
"Water pollution reduces the ecosystem services (such as providing drinking water) that the water resource would otherwise provide."
"Water pollution is either surface water pollution or groundwater pollution."
"Point sources have one identifiable cause, such as a storm drain, a wastewater treatment plant or an oil spill. Non-point sources are more diffuse, such as agricultural runoff."
"Pollution is the result of the cumulative effect over time."
"Contaminants may include organic and inorganic substances."
"A common cause of thermal pollution is the use of water as a coolant by power plants and industrial manufacturers."
"Control of water pollution requires appropriate infrastructure and management plans as well as legislation."
"Technology solutions can include improving sanitation, sewage treatment, industrial wastewater treatment, agricultural wastewater treatment, erosion control, sediment control, and control of urban runoff (including stormwater management)."

"Contaminants may include organic and inorganic substances. A common cause of thermal pollution is the use of water as a coolant by power plants and industrial manufacturers."
"Stressful conditions (e.g., changes of pH, hypoxia or anoxia, increased temperatures, excessive turbidity, changes of salinity)."
