Eutrophication is a process in which a body of water becomes overly enriched with nutrients, leading to excessive growth of algae and other aquatic plants. This can result in decreased oxygen levels in the water, which can harm fish and other aquatic organisms. Eutrophication is often caused by runoff of fertilizers and sewage from agricultural and urban areas, as well as other human activities that introduce excess nutrients into water bodies.

Eutrophication is the process by which a body of water becomes enriched with nutrients, leading to increased plant growth and a decline in water quality. The primary nutrients that can cause eutrophication are nitrogen and phosphorus.
Causes of Eutrophication:
- Agricultural runoff: Excess fertilizers and animal waste from farms can enter waterways, carrying nitrogen and phosphorus into the water.
- Wastewater discharge: Untreated or improperly treated sewage from homes and industries can discharge high levels of nutrients into water bodies.
- Urban runoff: Stormwater runoff from streets, parking lots, and lawns can carry fertilizers, pesticides, and organic matter into waterways.
Effects of Eutrophication:
- Algal blooms: Excess nutrients promote the rapid growth of algae, which can form dense mats on the water surface, blocking sunlight and reducing oxygen levels.
- Low oxygen levels: Algal blooms decompose, consuming oxygen and creating hypoxic or anoxic (oxygen-depleted) conditions, which can kill fish and other aquatic life.
- Fish kills: Low oxygen levels and toxic algal blooms can lead to mass fish kills, disrupting the aquatic ecosystem.
- Loss of biodiversity: Eutrophication can reduce water clarity and alter food webs, affecting the diversity and abundance of aquatic plants and animals.
- Harmful algal blooms (HABs): Certain types of algae can produce toxins that can harm humans, animals, and aquatic ecosystems.
Prevention and Control:
- Reducing nutrient inputs from agriculture: Implementing best management practices such as nutrient management plans and buffer strips to minimize fertilizer runoff.
- Improving wastewater treatment: Upgrading wastewater treatment plants to remove nitrogen and phosphorus before discharging effluent into water bodies.
- Controlling urban runoff: Using green infrastructure (e.g., rain gardens, bioswales) to capture and filter stormwater before it enters waterways.
- Public education: Raising awareness about the causes and effects of eutrophication and promoting responsible practices.
