Nutrient pollution occurs when too many nutrients, especially nitrogen and phosphorus, enter local water bodies. This causes excessive algae growth that depletes oxygen levels and harms ecosystems. Common sources of nutrient pollution include agricultural fertilizers, urban and suburban runoff, sewage, livestock waste, and stormwater drainage. Mitigation strategies involve nutrient remediation, total maximum daily load programs, discharge permits, and nutrient trading to reduce pollution from various sources.

4. Nutrient Pollution Effects
Population effects: excess growth of algae (blooming Algae);
Community effects: species composition shifts (dominant taxa);
Ecological effects: food web changes, light limitation;
Biogeochemical effects: excess organic carbon (eutrophication);
dissolved oxygen deficits (wntoxin production;
Human health effects: excess nitrate in drinking water (blue baby
syndrome); disinfection by-products in drinking water;
Biodiversity effects: excessive algae blooms
