Indications of stream pollution may include which condition?

Indications of stream pollution can prominently include a zone of degradation. This refers to areas in a stream where environmental conditions have significantly worsened, often due to the introduction of pollutants. In these zones, the natural balance and health of the ecosystem are disturbed, resulting in adverse effects on water quality, aquatic life, and overall ecological integrity.

Typically, a zone of degradation will show signs such as increased nutrient loads, toxic substances, or decreased oxygen levels, which can cause substantial harm to the aquatic environment. Consequently, the health of the stream is compromised, making it a clear indicator of pollution.

Understanding this concept highlights the importance of monitoring and managing water quality in streams to maintain healthy ecosystems.
