A plume in environmental science refers to a body of fluid, such as air, water, or contaminants, that spreads away from a source, often taking the shape of a column or a cloud. Plumes are commonly studied in the context of pollution, where they represent the dispersion of contaminants that can affect air quality, groundwater, or surface water.
For example, when contaminants are released into the atmosphere or a body of water, they do not just remain at the point of release. Instead, they disperse, creating a plume that can extend for varying distances depending on factors like wind speed, temperature, and the nature of the contaminants themselves. Understanding plumes is crucial for assessing environmental impact, designing remediation strategies, and protecting public health.
