"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."
The introduction of chemicals, nutrients, or other substances into water sources, which can result from agricultural practices such as irrigation and fertilization.
Types of water pollution: There are different types of water pollution, such as chemical pollution, bacterial pollution, and physical pollution.
Sources of water pollution: Industries, agricultural practices, sewage treatment plants, oil spills, and other human activities are some of the major sources of water pollution.
Water quality standards: Governments and regulatory agencies have set standards for water quality in different countries.
Effects of water pollution: Water pollution can have several negative effects on ecosystems and human health. These include the destruction of aquatic habitats, the reduction of the availability of clean drinking water, and the spread of waterborne diseases.
Industrial agriculture: Agriculture is a significant source of water pollution due to the use of fertilizers, pesticides, and other chemicals that can enter water bodies.
Best management practices: There are different best management practices that can be adopted by farmers and industries to minimize water pollution.
Water pollution control: Governments and regulatory agencies implement various measures to control water pollution in their countries.
Non-point source pollution: Non-point source pollution is the pollution that comes from diffuse sources and is difficult to control. This type of pollution is a significant challenge for water quality management.
Wastewater treatment: Wastewater treatment is the process of removing pollutants from wastewater before it is discharged into the environment.
Implementation of water pollution laws: Governments all over the world have set up laws and regulations to control and manage water pollution. The successful implementation of these laws is essential for managing water pollution.
Nutrient Pollution: This is a type of pollution that occurs when high levels of nutrients, such as nitrogen and phosphorus, are introduced into the water bodies. These nutrients promote the growth of algae and other aquatic plants that can deplete the oxygen levels in the water and negatively impact marine life.
Pesticide Pollution: This type of pollution occurs when pesticides and herbicides used in agriculture are washed into nearby water bodies. These chemicals can be toxic to aquatic life and also harmful for human health when consumed through contaminated water.
Sediment Pollution: This type of pollution can happen due to soil erosion and runoff from agricultural land into water bodies. Sediments can clog the waterways and also negatively impact aquatic life by restricting light and oxygen flow.
Livestock Waste Pollution: Farms with livestock can produce biodegradable waste that can contaminate the surrounding water bodies. The waste can carry harmful bacteria and viruses, and also contaminate groundwater sources.
Agricultural Runoff Pollution: Agricultural runoff refers to excess water that runs off from farm fields, carrying with it nutrients, chemicals, and soil particles. This excess water can lead to nutrient pollution, sediment pollution, and pesticide pollution in nearby water bodies.
Particulate Pollution: This type of pollution occurs due to the accumulation of non-soluble matter in water, such as residues from manure, fertilizers, and sewage. Particulate pollutants can damage aquatic life and degrade the water quality.
Acidification: Agricultural activity can cause acidity in water bodies by releasing acid-forming chemicals such as sulfur dioxide and nitrogen oxides. Acidification can lead to loss of aquatic organisms as well as affect the fishing industry.
Thermal Pollution: Water used for irrigation and industrial purposes can raise the temperature of nearby water bodies. This can negatively impact aquatic life by altering the ecosystem and reduce dissolved oxygen levels in the water.
Plastic Pollution: The agricultural industry can contribute to plastic pollution by using plastic packaging, nets, and materials that end up in water bodies. Plastic pollution can harm marine life and affect human health when ingested through seafood.
Heavy Metal Pollution: Inorganic fertilizers, pesticides, and herbicides can contain heavy metals like lead, cadmium, and mercury. These pollutants can accumulate in the food chain and can pose several health risks for people who consume seafood from contaminated water.
"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)."
