Study Notes
- Water pollution has multiple sources including untreated sewage water and industrial waste being intentionally discharged into rivers and seas.
- Surface runoff and rainwater in urban areas carry chemical pollutants into rivers, while in rural areas, agricultural fertilizers, pesticides, and animal feces make their way into water bodies, leading to nutrient increase and algae proliferation.
- Oil spills like the Rena oil spill in New Zealand in 2011 have massive environmental impacts, causing death of marine life and high cleanup costs.
- Human exposure to oil spills can result in skin irritation and rashes.
- Water pollution from natural disasters like floods and hurricanes often leads to contamination from mixing floodwaters with sewage water.
Explore the various sources of water pollution, including untreated sewage, industrial waste, chemical pollutants from urban runoff, agricultural fertilizers, oil spills, and contamination from natural disasters. Learn about the environmental impacts on marine life, cleanup costs, human health effects, and nutrient increase leading to algae proliferation.
