Which term describes the degradation of water bodies due to pollutants?

The term that describes the degradation of water bodies due to pollutants is "water quality impairment." This term specifically refers to the negative impacts on the physical, chemical, and biological characteristics of water as a result of contamination, which can come from various sources such as agricultural runoff, industrial discharges, or urban waste. When pollutants enter a water body, they can lead to a decline in water quality, making it harmful for aquatic life, human use, and overall ecosystem health.

Understanding water quality impairment is crucial in nutrient management, as excess nutrients, particularly nitrogen and phosphorus, can lead to problems such as algal blooms, which deplete oxygen in the water and harm aquatic organisms. Efforts to address water quality impairment often focus on reducing pollutant loads and restoring the health of affected water bodies.
