Life isn't a battle between good and evil, it's a battle between signal and noise.

Illustration of a Permeable Reactive Barrier Remediating a Contaminant Plume

PRB Illustration Info
Chemical waste deposited on or in the soil leaches through the soil and into the water table, contaminating the ground water with a dissolved phase of the contaminant. The contaminant 'plume' is then transported under the natural hydraulic gradient of the ground water to a properly positioned permeable reactive barrier. The plume impacts and passes through the reactive media present in the PRB, the contaminant is removed, reacted, or modified in some way, and the treated water passes out the other side of the PRB
