Eutrophication:

Eutrophication occurs when excessive nutrients, often from nonpoint source pollutants like fertilizers, cause an overgrowth of algae in aquatic ecosystems.

Best Management Practices (BMPs): BMPs are strategies and techniques used to minimize nonpoint source pollution by implementing practices like erosion control measures or proper waste management.
