D)contamination spreads out as it moves,forming a widening plume

Question

Quizplus · Accepted Answer

Contamination in groundwater spreads out as it moves, forming a widening plume. This spread can be affected by various factors such as the physical and chemical properties of the contaminant, the properties of the porous media through which the groundwater flows, and the direction and rate of groundwater flow. Contamination can move with the direction of groundwater flow or against it, depending on these factors. However, contamination generally does not move up the slope of groundwater as it moves in the direction of the steepest slope or gradient.
