Define the term “turbidity” in relation to water quality.

Turbidity refers to the cloudiness or haziness of water, which is primarily caused by the presence of suspended solids such as dirt, mud, and other particulates. When water has high turbidity, it indicates that there are many particles suspended in the water, which can impede light penetration and affect the biological processes within aquatic ecosystems. High turbidity can seriously compromise water quality by providing a medium for pathogens to thrive, decreasing oxygen levels, and affecting the ability of aquatic organisms to feed and reproduce.

Monitoring turbidity is an essential aspect of water quality assessment, particularly in drinking water and aquatic environments. It is a critical parameter because it can provide insights into the levels of contaminants or pollutants in the water. Therefore, understanding turbidity is vital for maintaining safe and healthy water standards for both human consumption and environmental health.
