Which physical characteristic is commonly assessed during water quality monitoring?

Temperature is a critical physical characteristic assessed during water quality monitoring because it plays a significant role in the overall health of aquatic ecosystems. It affects the metabolic rates of organisms living in the water, influencing growth, reproduction, and behavior. Additionally, temperature influences the solubility of gases, including oxygen, and can impact chemical reactions and the availability of nutrients.

Monitoring temperature helps identify changes in the water body that may result from natural processes or human activities, such as thermal pollution, which can harm aquatic life. By tracking temperature alongside other water quality parameters, environmental managers can better understand the conditions that affect aquatic ecosystems and make informed decisions regarding water resource management and conservation.
