Contaminant Plume
Contaminant plume
A contaminant plume is an extended region in groundwater or similar media where pollutant concentrations are higher than surrounding areas.
In context
Here, a contaminant plume is not an airborne cloud. Shape and extent depend on water flow, geology, and substance transport and reaction properties.
Example
Lower concentrations at one point near a pollution source require checking whether pollutants have moved to other locations. Do not equate improvement at one point with disappearance throughout the area.
Key distinction
Understand contaminant plumes by connecting results across locations and depths.
