Unveiling The Mystery: What's A Plume In Water Pollution?

A plume is a vertical body of one fluid moving through another, such as pollutants in groundwater. Groundwater flows along the gradient in the water table, taking a path that is perpendicular to the contours. Pollutants in the groundwater will flow in plumes along the same path.

Groundwater pollutants flow as a plume along with the groundwater

When a pollution source is introduced into the groundwater, the resulting plume will only affect areas down gradient from the source. Areas up gradient of the source, to the sides of the plume or below the plume will not be contaminated. Groundwater flows relatively slowly. On Long Island a typical rate of flow is about one foot per day near the water table, slower at greater depths. As the contaminant plume travels it becomes somewhat broader and more dilute as it slowly mixes with the surrounding cleaner water.

Liquids that are denser than water sink through the groundwater until they reach an aquitard. They then move slowly along the top of the aquitard along with the groundwater. Cemeteries are another source of pollution for groundwater. They are often located at the top of hills, and are thus up gradient from the local groundwater flow.

If the liquid that leaks is less dense than water and insoluble in water, it floats on top of the groundwater table. All chemicals are somewhat soluble in water. The dissolved fraction will travel as a plume in the groundwater.

Depending upon the original concentration of the plume and the distance the plume travels the contaminants may become so diluted that eventually the concentrations are lower than drinking water standards.

In hydrodynamics, a plume or a column is a vertical body of one fluid moving through another. Several effects control the motion of the fluid, including momentum (inertia), diffusion and buoyancy (density differences).

Plumes can pollute wells and surface water fed by the groundwater along the plume path
