What develops as a result of migration of the pollutant by groundwater that forms down-gradient with reference to the point source

Question

Quizplus · Accepted Answer

Migration of the pollutant by groundwater forms a contaminant plume, which spreads downstream or down-gradient from the point source. This occurs due to the movement of contaminated water through the permeable soil or rock layers. A contaminant plume defines a concentration gradient where the concentration of the pollutant decreases with distance from the point source. Therefore, option D, Contaminant plume, is the correct answer. Options A, B, and C do not adequately describe the phenomenon of pollutant migration by groundwater.
