1. Agricultural runoff: Excessive use of fertilizers on agricultural lands can result in the runoff of nutrients such as nitrogen and phosphorus into water bodies, leading to eutrophication.
2. Urban runoff: Stormwater runoff from urban areas can carry pollutants such as oil, grease, and heavy metals into water bodies, contributing to eutrophication.
3. Wastewater discharge: Untreated or poorly treated sewage and industrial wastewater can contain high levels of nutrients and organic matter, which can fuel algal blooms and eutrophication.
4. Deforestation: Clearing of forests can result in increased erosion and sedimentation in water bodies, which can lead to nutrient enrichment and eutrophication.
5. Climate change: Changes in temperature and precipitation patterns can alter nutrient cycling in water bodies, potentially leading to eutrophication.
6. Aquaculture: Intensive aquaculture practices can result in the release of excess nutrients and organic matter into water bodies, contributing to eutrophication.
7. Atmospheric deposition: Airborne pollutants such as nitrogen oxides can be deposited into water bodies through rainfall, contributing to nutrient enrichment and eutrophication.

Agricultural Activities:
- Excessive fertilizer runoff: Nitrogen and phosphorus from agricultural fertilizers can enter water bodies, leading to excess nutrient levels.
- Livestock manure: Manure contains high levels of nutrients that can leach into water sources.
Urbanization and Industrialization:
- Municipal wastewater discharge: Untreated or poorly treated wastewater from cities and industries contains nutrients, organic matter, and other pollutants.
- Industrial discharge: Factories and plants can release wastewater containing toxic chemicals, heavy metals, and nutrients.
Atmospheric Deposition:
- Nitrogen oxides (NOx) and ammonia (NH3): These air pollutants from combustion engines and agricultural activities can be deposited into water bodies, adding to nutrient levels.
Natural Factors:
- Natural weathering: Rocks and soil naturally release nutrients into water.
- Wetlands and riparian zones: These areas can filter nutrients from water, but excessive nutrient inputs can overwhelm their capacity.
- Biological processes: Decomposing organic matter can release nutrients into water.
Other Factors:
- Climate change: Warmer temperatures and increased precipitation can accelerate nutrient cycling and increase the prevalence of cyanobacterial blooms.
- Physical disturbances: Dredging, construction, and shoreline modification can release nutrients from sediments.
- Phosphates in detergents: Phosphates in laundry detergents can contribute to eutrophication if not properly removed during wastewater treatment.
- Excessive fertilizer runoff: Nitrogen and phosphorus from agricultural fertilizers can enter water bodies, leading to excess nutrient levels.
- Livestock manure: Manure contains high levels of nutrients that can leach into water sources.
